Introduction74LS138 is a 3-line to 8-line decoder / demultiplexer. The chip is designed to be used in high-performance memory-decoding or data-routing applications, requiring very short propagation delay times. In high performance memory systems these decoders can be used to minimize the effects of system decoding. The three enable pins of chip (in which Two active-low and one active-high) reduce the need for external gates or inverters when expanding.CatalogIntroductionI Full Adder CircuitII Responder CircuitIII Logic FunctionIV Full Subtractor CircuitV Three-input Majority VotingFAQOrdering & QuantityI Full Adder Circuit The full adder has 3 input terminals: An, Bn, Cn-1; 2 output terminals: Sn, Cn. The 74LS138 3-line to 8-line decoder has 3 data input terminals: A, B, C; 3 enable terminals and 8 output terminals. Here, the 3 data input terminals of the 3-line to 8-line decoder can be regarded as the 3 input terminals of the full adder. That is, the inputs A, B, and C of the 3-line to 8-line decoder correspond to the inputs An, Bn, and Cn-1 of the full adder respectively. Set the 3 enable terminals of the 3-line to 8-line decoder to the effective level to maintain normal operation. The key point here is to deal with the relationship between the 8 output terminals of the 3-line to 8-line decoder and the 2 outputs of the full adder.Use the output OUT (1, 2, 4, 7) of the 3-line to 8-line decoder as a 4-input or gate input, and the gate output as the sum of the adder. Use the output OUT ( 3, 5, 6, 7) of the 3-line to 8-line decoder as a 4-input or gate input, the gate output is used as the carry output of the adder. When the input of the adder is: a=1, b=0, ci=1, the input of the corresponding 3-line to 8-line decoder is A=1, B=0, C=1. The output of the decoder is out (5) = 1 and the rest is 0. According to the connection relationship designed above, S = 0, CO = 1, which satisfies the function of full adder.Figure 1. Full Adder CircuitII Responder CircuitFigure 2. Responder CircuitIII Logic FunctionF = ABC + A‘BC + AB’C= 111 + 110 + 101= Y7 + Y6 + Y5According to the rule of 74LS138, A is the low bit (LSB) and D is the high bit (MSB). The 74LS138 decoding output is low level effective. With 74LS10 NAND gate, the actual logic is input low level effective or gate.Figure 3. Circuit of Logic FunctionIV Full Subtractor CircuitFigure 4. Full Subtractor CircuitV Three-input Majority VotingThe device consists of a 3-line to 8-line decoder (74LS138) and two 4-input NAND gates (74LS20). There are three buttons for user. Press the button to agree, not to press means to reject. When no one presses the button, or when only one person presses the button, for example, S1 is pressed, but S2 and S0 are not pressed. The red light is on, the green light is off, and the buzzer is silent, indicating veto. When two or more people press the button, for example, if S1 and S2 are pressed, the red light will be off, the green light will be on, and the buzzer will sound to indicate a pass. Use 74LS138 decoder and four-input NAND gate 74LS20 to realize this logic function.Figure 5.

Opposite effectWhat's the difference between 74LS138D and 74LS138N？Those two are the same chip, D is SOP package, N is DIP package.What are the output characteristics of 74LS138 decoder？Under the premise that the enable terminals S1 (active high), S2 (active low), and S3 (active low) are valid at the same time, only one output terminal is low at a time (the rest are high);If the enable terminal is invalid, the output is all high level.What do the letters and numbers in 74ls138 stand for？74ls138 is a 3-8-line decoder. The number 74 represents the 74 series of the 54/74 series, and the 74 series has an operating temperature of 0 degrees to 70 degrees. LS is a series, representing the low-power Schottky series. 138 is the variety code.What’s the working principle of 74ls138?74LS138 working principle① When one strobe terminal (E1) is high level, and the other two strobe terminals (E2) and (E3) are low level, at the output terminals corresponding to Y0 to Y7, the binary code of address terminals (A0, A1, A2)  can be decoded at low level. For example: when A2A1A0=110, the Y6 output terminal outputs a low-level signal.②Using E1, E2 and E3, it can be cascaded to expand into a 24-line decoder; if an external inverter is connected, it can also be cascaded to expand into a 32-line decoder.③If one of the strobe terminals is used as a data input terminal, 74LS138 can also be used as a data distributor.④It can be used in 8086 decoding circuit to expand memory. 

DescriptionThe 2N7002 is a logic level MOSFET with a low on-state resistance. The mosfet has a low gate to source threshold voltage of 2.1V. Typically, this makes the mosfet suitable even for 3.3V application circuits. Since the mosfet has low on state resistance it has high efficiency during when the mosfet in on. Due to this property it can maintain high switching performance and hence used widely in power management applications.The mosfet also comes in a SMD package hence can be used for compact applications. One considerable disadvantage of the mosfet is its low drain current; it can provide a continuous current of 200mA and peaks currents upto 1A at maximum threshold voltage. Anything more than that will damage the mosfet.  CatalogDescriptionPin ConfigurationFeaturesDucuments and MediaPackage OutlineApplicationsAlternativesProduct ManufacturerOrdering & QuantityPin ConfigurationPin No.Pin NameDescription1GateControls the biasing of the MOSFET2SourceCurrent flows out through Source3DrainCurrent flows in through DrainFeaturesSuitable for logic level gate drive sourcesSurface-mounted packageVery fast switchingTrench MOSFET technologyDocuments and MediaDatasheet2N7002 N-Channel logic level MOSFET DatasheetPackage Outline ApplicationsLow current and Low Voltage switching applicationsDC-DC converterseMobility applicationsApplication where low on-state resistance is required.Power management applicationsAlternativesNTR4003, FDC666, FDC5582N7002 Equivalent P-Channel: BSS84, FDN358POther N-Channel MOSFETs: BS170N, IRF3205, 2N7000, IRF1010E, IRF540NProduct ManufacturerNXP Semiconductors N.V.

The 2N3906 is a widely used PNP bipolar junction transistor meant for general-purpose low-power amplifying or switching applications. It's designed for low current and power and medium voltage, and can be operated at moderately high speeds. This blog mostly introduces the PNP transistor 2N3906 's pinout, equivalents, application circuits, etc.  2N3906 PNP BJT breadbard switch circuit build step by stepCatalog2N3906 Pin Configuration2N3906 Features2N3906 Applications2N3906 Package2N3906 CircuitsHow Does 2N3906 Work in the PNP CircuitWhere to Use PNP Transistor 2N3906How to Use PNP Transistor 2N39062N3906 Functional Equivalents2N3906 Popularity by Region2N3906 Market Price Analysis2N3906 ManufacturerComponent DatasheetFAQ2N3906 Pin ConfigurationPin NumberPin NameDescription1EmitterCurrent Drains out through emitter2BaseControls the biasing of transistor3CollectorCurrent flows in through collector2N3906 FeaturesBi-Polar PNP TransistorDC Current Gain (hFE) is 300 maximumContinuous Collector current  (IC) is 200mAEmitter Base Voltage (VBE) is 5VBase Current(IB) is 5mA maximumCollector Emitter Voltage (VCE) is 40VCollector Base Voltage (VCB) is 40VAvailable in  To-92  Package2N3906 ApplicationsUsed to switch high voltage low current loadsOptimal for loads with high peak voltage upto 40VIt is used in the various switching applicationsUsed in inverter and converter circuitsUsed for making siren or dual Led or Lamp flasherCan be used in Darlington Pair2N3906 Package2N3906 CircuitsDelay and Rise Time Equivalent Test Circuit Storage and Fall Time Equivalent Test CircuitHow Does 2N3906 Work in the PNP Circuit Below it's the circuit for connecting a PNP transistor, which 2N3906 functions as a switch or an amplifier. So +3V is connected to the emitter of the transistor. And a normally open pushbutton is connected to the base of the transistor. Unless it is pressed, normally no current flows into the base of the transistor. Thus, it is fully on when not pressed. Therefore, the LED connected to the collector of the PNP transistor will be on. However, if the push button is pressed, the transistor will turn off and the LED will shut off. This is because the base voltage will be greater than the emitter voltage, which blocks current flow. And this is how a basic PNP transistor circuit works.Where to Use PNP Transistor 2N3906 The 2N3906 is a commonly used PNP transistor. It is very much similar to the bc557 transistor except that it has a high collector to emitter voltage and hence high voltage loads can be toggled. This transistor has only a gain value of 300, hence not suitable for amplifier circuits. So if you looking for a PNP transistor that could switch high voltage loads within 0.2A then this 2N3906 transistor might be the right choice for you.How to Use PNP Transistor 2N3906 The 2N3906 transistor is commonly used as a switching device. When used as a switch, it can be operated in the saturation region and cut-off region. In the PNP transistor, by default, it’s in ON state, but not to be said perfectly ON until the base pin is not grounded. If we provide ground to the base pin then the transistor will be in reverse biased and said to be turned ON. If supply is provided to the base pin it stops conducting current between emitter and collector and is said to be in an OFF state. For the protection of the transistor, a resistance was added in series with it. For finding the value of that resistor you can use the formula: RB = VBE / IB Where, the value of VBE will be 5v for this transistor. The maximum value of providing base current is 200mA. So, from that you can find the value of resistance to be added in series with it. In the below circuit the base emitter voltage  (VBE) is 0V (Grounded) hence the PNP transistor conducts and the motor rotates. If made high (5V) the motor will stop rotation. Note that for PNP transistors the loads should be connected in the collector side as shown below. Also, note that the load current should be less than 200mA (here 140ma). 2N3906 Functional Equivalents2N3906 Popularity by Region2N3906 Market Price Analysis2N3906 ManufacturerON Semiconductor (Nasdaq: ON) is driving energy efficient innovations, empowering customers to reduce global energy use.
