Ring oscillatorThe experimental circuit of a non gate ring self-excited multivibrator with RC delay circuit is shown in the figure. The oscillation circuit is composed of non gate IC1, IC2, IC3, and timing circuit elements RP and C. The rectangular wave signal is output by IC3. R1 is a protective resistor to avoid damage to IC 3 gate circuit when timing capacitor C is reverse discharged. Not gate IC4 makes the oscillator output rectangular wave with better waveform.Oscillation frequency estimation f > 1 / 2.3RC T> 2.3RCThe resistance value of the timing resistor is selected in the range of 100-10002. The timing capacitor C has a large value range, from several hundred picofarads (pF) to several hundred microfarads, which can make the oscillation frequency range from several megahertz to several hertz. Replace the timing resistor with a potentiometer  (1.5k92), which can continuously adjust the oscillation frequency and has larger coverage. The chip used is 74LS04.II Symmetrical Square-wave OscillatorThe figure shows the experimental circuit of the non-gate symmetrical square-wave self-excited multivibrator. Because the circuit is symmetrical, the duty cycle of output oscillation waveform is 1:1, which is a square wave, so it is called a symmetrical square wave oscillator. In the oscillation circuit, the output of non gate IC1 is coupled to the input of non gate IC2 via a timing capacitor C2. Also, the IC2 output is coupled to the IC1 input via C1. Two non gates are coupled with each other through capacitors to form a positive feedback closed-loop circuit, which can produce square-wave oscillation. When R1 = R4 = R, C1 = C2 = C, the estimation formula of oscillation frequency is as follows: f≈1/RC. The oscillation period T ≈ RC.Figure 2. Symmetrical Square-wave OscillatorIII Simple self-excited MultivibratorThe figure shows a simple non gate self-excited multivibrator experimental circuit. It is composed of non-gate oscillator IC1, IC2, inverter IC3, red and green light-emitting diodes and power supply system GB. IC1 and IC2 are the switching links of the oscillator. R1 and C timing circuits produce delay positive feedback signals to control the switch to turn on and off periodically, so that IC2 outputs rectangular wave. The inverter IC3 makes the red and green LEDs and the oscillator flash alternately.Figure 3. Simple self-excited multivibratorIV Circuit of Crystal Oscillator and Frequency DividerFigure 4. Circuit of Crystal oscillator and frequency dividerV FM Wireless MicrophoneWireless microphones are available everywhere on the market, but their circuits are all made up of LC oscillators or quartz crystal oscillator circuits. As we all know, the NAND gate has the function of magnification and phase inversion. Therefore, as long as three NAND gates are connected, a ring oscillator is formed. Coupled with the FM circuit, it can also be made into a wireless microphone.Figure 5. FM wireless microphone74LS04 is a TTL integrated circuit with six single-input NAND gates. The author uses three of them to make an oscillator. When the supply voltage is 5V, the oscillation frequency is about 90mhz. When the power supply voltage decreases, the frequency decreases; when the supply voltage increases, the frequency also increases. Of course, its oscillation amplitude will also change, but the effect is not significant. In this way, the author uses the method of changing the power supply voltage to change the frequency (that is, to achieve frequency modulation). The specific method is to use the output of BA328, an audio amplifier integrated circuit, as its power supply.BA328 is an amplifying circuit of the recording head. When it is used for tape signal compensation and equalization, an RC series-parallel network should be connected between the first and the second pins, but it is used for linear amplification, so only a 100kw-130kw resistor is needed. The voltage of the output terminal (pin) of BA328  should be equal to one-half of the voltage of the pin (power supply). If the power supply voltage is 12V, there should be a 6V output. If it is not correct, the resistance should be adjusted. In addition, the 1kW resistor in the figure is used to adjust the magnification. If it is reduced, the gain will be increased. When speaking to an electret microphone, the voltage at the output (PIN) can change rapidly from 5.8v to 6.2V. This voltage is sent to the foot of 74LS04  to make it generate an FM signal, which is amplified and isolated by the fourth NAND gate and sent to the antenna.FAQWhat does 74LS04 contain?Six gates that perform the logic INVERT functionWhat is 74LS04?74LS04 is a member of 74XXYY IC series. The 74-series are digital logic integrated circuits. 74LS04 IC has six NOT gates. These NOT gates perform Inverting function. Hence name HEX INVERTING GATES.What is the function of ic 74ls04?74LS04 Hex NOT Gate IC. 74LS04 is a 2 input quadruple 8-bit NOT gate IC. Inverter in logic converters is an electronics device whose basic functions are to invert the incoming logic weather it is HIGH or LOW. They are also known as NOT gates.What is a hex inverter?A hex inverter is a type of an integrated circuit that contains six inverters. Many sophisticated digital devices use inverters, including multiplexers, decoders, and state machines.  An inverter circuit's main function is to output the voltage representing the opposite level to its input.Why is NOT gate called an inverter?A NOT gate, often called an inverter, is a nice digital logic gate to start with because it has only a single input with simple behavior. A NOT gate performs logical negation on its input. In other words, if the input is true, then the output will be false.

I IntroductionThe LM311 devices are single high-speed voltage comparators. The devices are designed to operate from a wide range of power supply voltages, including ±15-V supplies for operational amplifiers and 5-V supplies for logic systems. The output levels are compatible with most TTL and MOS circuits. These comparators are capable of driving lamps or relays and switching voltages up to 50 V at 50 mA. All inputs and outputs can be isolated from the system ground. The outputs can drive loads referenced to ground, VCC+ or VCC−. Offset balancing and strobe capabilities are available, and the outputs can be wire-OR connected. If the strobe is low, the output is in the off state, regardless of the differential input.CatalogI IntroductionII Precautions of LM3112.1 Choose Components Reasonably2.2 Increase Amplitude of Input Signal2.3 Add Filtering Appliances to Output of Comparator2.4 Adopt Lagging TechnologyFAQOrdering & QuantityII Precautions of LM311LM311 is a commonly used linear comparator, which is widely used in comparison and shaping circuits, as is shown in Figure 1. Figure 1. LM311 Circuit DiagramHowever, LM311 often has unexpected problems in the application, that is, the output pulse signal is not as ideal as theoretical analysis. Instead, high-frequency oscillation occurs near the front and back edges of the output pulse, as shown in Figures 2 and 3. Figure 2. High Frequency Oscillation before Output Pulse Figure 3. High Frequency Oscillation after Output PulseWhen the input signal Vi amplitude of the LM311 is smaller and the frequency is lower, the high-frequency oscillation is more serious. This kind of waveform containing high-frequency oscillation cannot be used directly. It will cause misoperation to subsequent circuits, such as frequency measurement. Therefore, this situation must be paid attention to, and try to avoid or eliminate the high-frequency oscillation. The following will give a brief analysis of the causes of oscillations, and at the same time put forward several methods to effectively avoid eliminating oscillations on the basis of experiments.Figure 4. LM311When a high-speed comparator is used for high-speed input signals and low source impedance input signals, the normal output response should be fast and stable. However, when the input signal is a slowly varying signal or a high-impedance signal source (1.0KΩ-10KΩ), the comparator may oscillate suddenly at the comparison threshold point, which is caused by the high gain and wideband of the comparator, and the presence of interference is also one of the direct causes of this oscillation. In application, to avoid this kind of oscillation and instability, careful consideration should be made in advance and overall arrangements should be made. The following will propose several effective methods to avoid and overcome oscillations:2.1 Choose Components ReasonablyReasonably arranging the occurrence of structural oscillations has a lot to do with structural arrangements. The output signal should be far away from the input terminal pin, and should also be far away from the two balanced terminal pins, because the feedback signal sensing or touching any pin may almost cause oscillation. If the comparator uses a resistor at the input, its position and resistance are worth considering. The resistance should be placed near the tube base, and the general resistance value should be less than 10K (or even less), please refer to the corresponding manual when using. The positive and negative power supply should add 0.1μ filter capacitor to filter out the interference of the power supply, and put the capacitor near the pin. The two balanced ends should be properly handled. When not in use, they can be shorted together. For specific use, you can also refer to the relevant manual.2.2 Increase Amplitude of Input SignalThe magnitude of the input signal amplitude is directly related to the oscillation. Experiments show that the smaller the signal amplitude, the lower the frequency, the greater the possibility of oscillation. The following will make a simple analysis of the above conclusions. If there is a zero-crossing comparator, the input signal is Vi=V0sinω0t. The slope of the signal at t=0 is:The amount of voltage change in △t time is: △Vi=K·△t=V0sinω0t, which shows that △Vi is proportional to V0,ω0, that is, the greater the amplitude of the input signal, the higher the frequency of the signal. Then in the △t time, the longer the amplitude change of V is, when dvi/dt is large enough, the input signal will quickly cross the comparison threshold, so as to achieve the purpose of eliminating oscillation. Because the input voltage range of the comparator is generally relatively wide (for example: the voltage input range of the LM311 is ±30V), this method is the most simple and feasible. The experiment proves that as long as the amplitude of the input signal is greater than 0.7V, this design can work reliably in the range of 10Hz ~ 60KHz, continue to increase the voltage amplitude, the working range can be extended to the low frequency end.2.3 Add Filtering Appliances to Output of ComparatorPulling a resistor at the output of the comparator and connecting a capacitor with an appropriate capacity has a significant effect on filtering and reducing oscillation. The capacity of the capacitor should be determined on the basis of the experiment. The capacity of the capacitor should not be too large, otherwise the leading edge of the output pulse will be deteriorated. It was found in the experiment that this negative effect is particularly serious at higher frequencies, and even make the pulse amplitude smaller, so that the counter of the subsequent stage can not work, the situation is shown in Figure 5. Figure 5. Pulse Amplitude at Higher FrequenciesTherefore, this method has certain limitations in the application, and the reasonable choice of capacitance is the key to applying this method. Of course, the deteriorated front can be restored by the 74LS14 with a shaping effect. The negative effect of this method is to shift the original pulse front backward. In this design, capacitance C=0.01μ is taken. Within the range required by the system, the value of the pull-up resistor that the circuit can work reliably cannot be too large. In this design, R=510Ω.2.4 Adopt Lagging TechnologyIn the comparison circuit, when the input signal reaches the comparison level, the comparator should be reversed immediately, but if the measured signal is superimposed with a certain amount of interference, the comparator may oscillate near the comparison level, as shown in the following figure (Figure 6-7).Figure 6. Output of a Common Zero-crossing ComparatorFigure 7. Output with Lag TechnologyThe effective method to overcome the oscillation of the comparator is to use the lag technology, that is, add a small amount of positive feedback to its non-inverting end. The comparison level of the lag comparator is no longer a single level, but has two power levels near the original comparison level. In general, for the circuit in figure 8, the upper comparison level is represented by V+H, and the lower comparison level is represented by V+L.Figure 8. Circuit with Two LevelsThe hysteresis voltage can be adjusted by R1 and R2. As long as △V is selected properly, the oscillation phenomenon of the comparison circuit can be eliminated. Therefore, the anti-interference ability is greatly improved, but the presence of the lag level △V will make the detection sensitivity worse. Therefore, △V should not be too large, usually R1≤R2. For the LM311 comparator, adding 3mv of hysteresis will eliminate the oscillation in the circuit.Therefore, we must consider carefully and treat separately when using LM311. Only in this way can we be handy when using it.FAQWhat are the LM311 devices?Single high-speed voltage comparatorsWhat are the LM311 devices capable of?Driving lamps or relays and switching voltages up to 50 V at 50 mAWhat are available in the LM311 devices?Offset balancing and strobe capabilitiesHow to use LM311?LM311 is a single-channel comparator. When using it, connect the reference voltage and the compared signal voltage to its non-inverting and inverting input terminals (pin 2 and pin 3), and its output is the result of the comparison. If you want the foward output result, pin 7 is connected to the positive power supply and pin 1 is the output. If the result is to be output in reverse, pin 1 is grounded and pin 7 is the open collector output.lm311 and lm393 are both voltage comparators, so what is the difference between them?LM311 is single voltage comparaotor, LM393 is dual voltage copatpr. LM311 has a load current of up to 50MA and a voltage of 40V. It can drive relays with a minimum power supply voltage of 5V.The LM393 load current is 16MA, and the minimum voltage is 2V for a single power supply.What’s the difference between LM311 and LM111?Their functions are the same, and the 1XX series can be used in harsher environments.The 3XX series can only be used in a commercial environment, typically the applicable temperature range of the device.The price of 1xx is much more expensive than 3xx.What does the 5 and 6-pin balance strobes of LM311 mean?The function of balancing the mirror current of the reverse circuit is realized by connecting a potentiometer in the middle. In addition to the balance function, the 6 pin also has a strobe function, and the 6 pin can be grounded through the transistor drive circuit for strobe output.What is the difference between lm311 voltage comparator dual power supply and single power supply?The comparators are all open-collector outputs, without load resistance, they cannot output voltage signals.Dual power supplies can detect signals lower than 0, and single power supplies can only detect signals higher than 0.Can the lm311 comparator be powered by a positive and negative five-volt dual power supply?Of course, LM311 can be powered by ±5V dual power supply. Its requirement for working power supply is that the voltage difference between the positive and negative power supply (or single power supply voltage) is at least 3.5V and the maximum is 30V, as long as it is within this range.

As shown in the circuit we have two push buttons Q1 and Q2 which act as controls inputs for bridge-A. These logic inputs are provided by the Microcontroller or Microprocessor in application circuits. The four diodes are FLYBACK diodes used for protecting the IC form inductive voltage spikes. The enable pin is pulled high through a resistor so bridge-A will be functioning all the time. If it’s pulled to ground the bridge-A will be disabled no matter the input control logic.After all the circuits are setup we need to press the buttons Q1 and Q2 to change the flow of current between pins OUT1 and OUT2.  The logic control table is given below.INPUTSFUNCTIONQ1=HIGH, Q2=LOWForward currentQ1=LOW,Q2=HIGHReverse currentQ1=Q2Fast MOTOR stopSo if only Q1 is pressed, the current flows from OUT1 to OUT2. With that MOTOR rotates clockwise direction. If only Q2 is pressed, the current flows from OUT2 to OUT1. With that MOTOR rotates anti-clockwise direction. If both buttons are pressed or released simultaneously the MOTOR comes to stop immediately. In this way, we can control the motor rotation using the L298 chip.L298 ApplicationsRobotic armsRobotsRelay driversVending machinesIndustrial machinesEngineering systemsMeasuring instrumentsHobby projectsL298 Compare with Other MotorsWith so many motor drivers currently such as Servo Motors and stepper motor s, what really are the differences between the motor drivers and which one to choose?

DescriptionLM339 (Quad differential comparator) consists of four independent voltage comparators. It is a common integrated circuit and is mainly used in high-voltage digital logic gate circuits. Using LM339 can easily form various voltage comparator circuits and oscillator circuits.CatalogDescriptionComponent DatasheetLM339 PinoutBasic ParametersFeaturesApplicationPin Function ListCircuit DiagramPackageElectrical CharacteristicsInstructionsProduct ManufacturerFAQOrdering & QuantityComponent DatasheetComparator Datasheet  LM339 Datasheet LM339 PinoutLM339 PinoutBasic ParametersParameter nameSymbolNumerical valueunitsupply voltageVCC±18 or 36VDifferential mode input voltageVID±36VCommon mode input voltageVI－0.3~VCCVPower dissipationPd570mWWorking environment temperatureTopr0 to ＋70℃Storage temperatureTstg－65 to 150℃Features Low voltage offset, generally 2mV The common-mode voltage range is very large, from 0v to the power supply voltage minus 1.5v The internal resistance limit to the signal source is very wide Single Supply Operation: 2-36V Dual  Supply Operation: ±1V-±18V The potential of output can be selected flexibly and convenientlyLM339 is similar to the operational amplifier with non-adjustable gain. Each comparator has two inputs and one output. One of the two input terminals is called the non-inverting input terminal, which is represented by "+", and the other is called the inverting input terminal, which is represented by "-". When comparing two voltages, add a fixed voltage as a reference voltage at any input terminal, and add a signal voltage to be compared at the other terminal. When the voltage at the "+" terminal is higher than the "-" terminal, the output tube will cut off. When the voltage of the "-" terminal is higher than the "+" terminal, the output tube is saturated. The voltage difference between the two input terminals is greater than 10mV, which can ensure that the output can be reliably switched from one state to another state. Therefore, it is ideal to use the LM339  in weak signal occasions. The output terminal of LM339 is equivalent to a crystal transistor that is not connected to the collector resistor. When using, the output terminal to the positive power supply generally needs to be connected to a resistor (called pull-up resistor). Choosing pull-up resistors with different resistance values will affect the value of the high potential at the output. Because when the output transistor is off, its collector voltage basically depends on the value of the pull-up resistor and the load. In addition, the output of each comparator is allowed to be connected together.ApplicationIndustrialAutomotive Infotainment and ClustersBody Control Module Power SupervisionOscillatorsPeak DetectorsLogic Voltage Translation Pin Function ListPin NumberPin functionSymbolPin NumberPin functionSymbol1Output 2OUT28Inverting input 31N-(3)2Output 1OUT19Forward input 31N+(3)3Power SupplyVCC +10Inverting input 41N-(4)4Inverting input 11N-(1)11Forward input 41N+(4)5Positive input 11N+(1)12Power SupplyVcc6Inverting input 21N-(2)13Output 4OUT47Forward input 2OUT2(2)14Output 3OUT3Circuit DiagramLM339 Circuit DiagramPackage LM339 PackageElectrical Characteristics VCC=5.0V, Tamb=25℃, unless otherwise statedParameter nameSymbolTest conditionsMinimumTypicalMaximumunitInput offset voltageVIOVCM=0 to VCC-1.5 VO(P)=1.4 V, Rs=0-±1.0±5.0mVInput offset currentIIO--±5±50nAInput bias currentIb--65250nACommon mode input voltageVIC-0-VCC-1.5VQuiescent CurrentICCVCC= ＋5V, no load-1.12.0mAVCC= ＋30 V, no load-1.32.5mAVoltage gainAVVCC=15V, RL＞15kΩ-200-V/mVSink currentIsinkVi(-)＞1V, Vi(+)=0V, Vo(p)＜1.5V616-mAOutput leakage currentIOLEVi(-)=0V, Vi(+)=1V, VO=5V-0.1-nAInstructions The LM339 series are high gain, wide bandwidth devices which, like most comparators, can easily oscillate if the output lead is inadvertently allowed to capacitively couple to the inputs via stray capacitance. This shows up only during the output voltage transition intervals as the comparator changes states. Power supply bypassing is not required to solve this problem. The standard PC board layout is helpful as it reduces stray input-output coupling. Reducing this input resistors to <10 k reduces the feedback signal levels and finally, adding even a small amount (1 to 10 mv) of positive feedback (hysteresis) causes such a rapid transition that oscillations due to stray feedback are not possible. Simply socketing the IC and attaching resistors to the pins will cause input-output oscillations during the small transition intervals unless hysteresis is used. If the input signal is a pulse waveform, with relatively fast rise and fall times, hysteresis is not required.All pins of any unused comparators should be tied to the negative supply.The bias network of LM339 establishes a drain current that is independent of the magnitude of the power supply voltage over the range of from 2 V to 30 V.It is usually unnecessary to use a bypass capacitor across the power supply line.The differential input voltage may be larger than V+ without damaging the device. Protection should be provided to prevent the input voltages from going negative more than －0.3 VDC (at 25 ℃). An input clamp diode can be used as shown in the applications section.The output of the LM339 is the uncommitted collector of a grounded-emitter NPN output transistor. Many collectors can be tied together to provide an output OR ing function. An output pull-up resistor can be connected to any available power supply voltage within the permitted supply voltage range and there is no restriction on this voltage due to the magnitude of the voltage which is applied to the V＋ terminal of the LM1339 package. The output can also be used as a simple SPST switch to ground (when a pull-up resistor is not used). The amount of current which the output device can sink is limited by the drive available (which is independent of V＋) and the β of this device. When the maximum current limit is reached (approximately 16 mA), the output transistor will come out of saturation and the output voltage will rise very rapidly. The output saturation voltage is limited by the approximately 60 Ω RSAT of the output transistor. The low offset voltage of the output transistor (1 mV) allows the output to clamp essentially to ground level for small load currents.  Product ManufacturerTexas Instruments Inc.

The devices consist of four independent voltage comparators that are designed to operate from a single power supply.What is the difference between LM324 and LM339?The LM324 has a complementary output while the LM339 is open collector. In the complementary output, current can flow in either direction as required (either source or sink) while the open collector output can only sink current.How does LM339 comparator work?The LM339 is a quad op amp comparator. A comparator works by a simple concept. Each op amp of a comparator has 2 inputs, a inverting input and a noninverting input. If the inverting input voltage is greater than the noninverting input, then the output is drawn to ground.What is comparator ic?A comparator is an electronic circuit, which compares the two inputs that are applied to it and produces an output. The output value of the comparator indicates which of the inputs is greater or lesser. Please note that comparator falls under non-linear applications of ICs.What is the replacement for LM339?LM311, LM324, LM397, LM139, LM239, LM2901What is a comparator circuit?A comparator circuit compares two voltages and outputs either a 1 (the voltage at the plus side; VDD in the illustration) or a 0 (the voltage at the negative side) to indicate which is larger. Comparators are often used, for example, to check whether an input has reached some predetermined value.What is the use of LM339?LM339 is used in applications where a comparison between two voltage signals is required. In addition with four of those comparators on board the device can compare four pairs of voltage signals at a time which comes in handy in some applications.What type of circuit is LM339 mainly used in?High-voltage digital logic gate circuitsWhat type of circuits can LM339 form?Oscillator circuitsIn what situations is the LM339 ideal to use?Weak signal occasions
