The HCF4094 is an 8-stage, serial shift register having a storage latch associated with each stage for strobing data from the serial input to parallel buffered 3-state outputs. The parallel outputs may be connected directly to common bus lines. Data are shifted on positive clock transition. The data in each shift register stage are transferred to the storage register when the STROBE input is high. Data in the storage register appear at the outputs whenever the OUTPUT-ENABLE signal is high. Two serial outputs are available for cascading a number of HCF4094 devices. Data are available at the QS serial output terminal on positive clock edges to allow for high speed operation in a cascaded system in which the clock rise time is fast. The same serial information, available at the Q’S terminal on the next negative clock edge, provides a means for cascading HCF4094 devices when the clock rise time is slow. HCF4094YM013TR Related Video IntroductionHCF4094YM013TR Video Description: Shift registers are devices that are quite popular when using micro controllers as they can be used to expand the number of inputs or outputs available.

The most common of these are called Johnson counters and ring counters. What is counter register?A counter register is a sequential circuit with n + 1 inputs and n outputs. It differs from an ordinary counter in that it can also function as a register. It differes from a register in that when not explictly loaded, it works as a counter, rather than maintaining its previous value. What is the difference between counters and shift registers?A counter is a special case of a register. Shift registers are a type of sequential logic circuit, mainly for storage of digital data. They are a group of flip-flops connected in a chain so that the output from one flip-flop becomes the input of the next flip-flop.

The RC is the collector Resistor and changing this value will change the frequency response of the circuit as well as it will control the DC gain by controlling the collector current. R1 and R2 are used as a voltage divider for biasing the JFET.   A typical value for 12V operation could be: R1 = 100k, R2 = 10k, RC= 10k, and C1, C2 can be 1uF ceramic capacitors.   2N3819 Interfacing Diagram   Where to use 2N3819? This N-channel JFET can be used for low side switching only. Because N-channel JFETs are used to drive low-side power paths only. But if you want to drive a high-side load, you can use any other P-channel JFET. Another important point here to note here is that the drain current of 2N3819 JFET is 100mA. Hence, it will be used for an application that only requires less than 100mA Drain current.   2N3819 Circuit Diagram The following circuit shows the example of 2N3819 JFET as a switch. A DC voltmeter is connected between Drain and sourcr terminal to measure voltage across Drain terminal.   When zero voltage is applied to the Gate terminal of N-channel JFET, FET  operates in saturation mode and It acts like a closed circuit and almost zero voltage appears across the Drain terminal as you can see on the DC voltmeter  . Similarly, when enough negative voltage is applied to Gate terminal of N-channel JFET, FET operates in the cut-off region and It acts as an open circuit and input voltage source (+25V) appears across Drain terminal as you can see on the DC voltmeter.    N-Channel JFET as a Switch   The circuitry for an AC  field detector is shown above:   AC field detector Circuit Diagram   It will explain the working of 2N3819 N-Channel JFET as a field detector. The transistor source terminal is connected with 6-12 Volts of power source to supply voltage to 555 Timer IC. The IC  is further connected with an LED, which brightens when the timer turns on, and a buzzer that produces sound whenever a signal is detected. An antenna is connected to the gate of 2N3819 to detect the  AC field. Whenever the antenna senses a charge or a wave, it will induce a voltage and pass it to the gate terminal. The change in the gate voltage alters ID and activates the TimerIC,  As a result, the led starts to blink, showing the activation of the IC.  and the buzzer produces the sound to indicate that a charge is detected by the antenna.   2N3819 Package The following diagram shows the 2N3819 package.   2N3819 Package   2N3819 Specification SpecificationValuePackageTO-92-3Transistor PolarityNMaximum Gate Source Voltage-25 VZero-Gate Voltage Drain Current20 mAMaximum Drain Gate Voltage25 VMountingThrough HolePackagingBoxTransistor TypeJFETNo. of Pins3 Pin   2N3819 Manufacturer For over 40 years, NTE Electronics, Inc.  has been a leading supplier of high-quality NTE and ECG brand name electrical and electronic components.

An n-type channel is formed between two p-type layers which are connected to the gate. Majority carrier electrons flow from the source and exit the drain, forming the drain current.   What is the difference between N channel and P-channel JFET? There are two types of JFET: n-channel and p-channel. Due to the fact that electrons move faster than holes, n-channel JFETs are more common than p-channel JFETs. The conduction level in a bipolar junction transistor (BJT) depends on two charge carriers – electrons and holes.   Which is the majority charge carrier in n-channel JFET? Electrons are the majority charge carrier in N-channel JFET. The channel formed is in between source and drain which are made of p-type semiconductor material.   What is the direction of current flow in N-channel JFET? When a voltage greater than pinch off is applied, the current starts flowing from Drain to source.   What does N channel mean? An N-Channel MOSFET is made up of an N channel, which is a channel composed of a majority of electron current carriers. The gate terminals are made up of P material. Depending on the voltage quantity and type (negative or positive) determines how the transistor operates whether it turns on or off.

High-side means the current travels from the supply through the mosfet to the load and then to ground. Another way to put that is: Low-side = mosfet source to ground, drain to load, load to supply. High-side = mosfet drain to supply, source to load, load to ground.   What does a high side switch do? High-side switches are used to turn electrical loads ON and OFF by switching the positive (high-) side of the load supply.   When would you use a high side switch? High-side switching is the preferred switching technique in situations where short circuits to ground are likelier to occur than short circuits to the positive power line. Think for instance of cars or machines where most of the structure or body is connected to ground.   What is difference between high side and low side current sensing? The difference is based off on the location of the sense resistor. Low side sensing is between load and ground, with high side sensing between power and the load. A high side current sensor, with a precision trimmed preset gain of either 20, 50, or 100.   How do you drive a high side MOSFET? Here when the high-side MOSFET is off, a capacitor is charged from the driving voltage. The capacitor charges through the load or a supporting low-side MOFSET. When the high-side MOSFET is to be turned on/driven, the voltage on the capacitor is used to drive the high-side MOSFET.

Codecs are compression technologies and have two components, an encoder to compress the files, and a decoder to decompress. There are codecs for data (PKZIP), still images (JPEG, GIF, PNG), audio (MP3, AAC) and video (Cinepak, MPEG-2, H.264, VP8). There are two kinds of codecs; lossless, and lossy. Lossless codecs, like PKZIP or PNG, reproduce the same exact file as the original upon decompression.   Why do we need PMIC? PMICs are frequently used to power small, battery-operated devices since the integration of multiple functions into a single chip results in more efficient use of space and system power.   What is an audio codec used for? An audio codec converts analog audio signals into digital signals for transmission or encodes them for storage. A receiving device converts the digital signals back to analog form using an audio decoder for playback. An example of this are the codecs used in the sound cards of personal computers.

During the hold condition, DQ1 is High-Z. DQ0 and C are "Don’t Care." To start the hold condition, the device must be selected, with S# driven LOW.W#/VPPInputWrite protect: The W#/VPP signal is both a control input and a power supply pin. The two functions are selected by the voltage range applied to the pin. If the W#/VPP input is kept in a low voltage range (0 V to VCC) the pin is seen as a control input. The W# input signal is used to freeze the size of the area of memory that is protected against program or erase commands as specified by the values in BP2, BP1, and BP0 bits of the Status Register. VPP acts as an additional power supply if it is in the range of VPPH, as defined in the AC Measurement Conditions table. Avoid applying VPPH to the W#/VPP pin during a BULK ERASE operation.VCCPowerDevice core power supply: Source voltage.VSSGroundGround: Reference for the VCC supply voltage.DNU–Do not use. M25P80-VMP6TG TR Block DiagramFigure: M25P80-VMP6TG TR Block Diagram M25P80-VMP6TG TR FeaturesSPI bus-compatible serial interface8Mb Flash memory75 MHz clock frequency (maximum)2.7V to 3.6V single supply voltagePage program (up to 256 bytes) in 0.64ms (TYP)Erase capability– Sector erase: 512Kb in 0.6 s (TYP)– Bulk erase: 8Mb in 8 s (TYP)Write protection– Hardware write protection: protected area size defined by nonvolatile bits BP0, BP1, BP2Deep power-down: 1µA (TYP)Electronic signature– JEDEC-standard 2-byte signature (2014h)– Unique ID code (UID) and 16 bytes of common Flash interface (CFI) data– RES command, one-byte signature (13h) for backward compatibilityMore than 100,000 write cycles per sectorMore than 20 years data retentionAutomotive-grade parts availablePackages (RoHS-compliant)– SO8N (MN) 150 mils– SO8W (MW) 208 mils– VFDFPN8 (MP) MLP8 6mm x 5mm– UFDFPN8 (MC) MLP8 4mm x 3mm M25P80-VMP6TG TR DatasheetYou can download the datasheet from the link given below:M25P80-VMP6TG TR Datasheet M25P80-VMP6TG TR SpecificationsTypeDescriptionCategoryIntegrated Circuits (ICs)MemoryMfrMicron Technology Inc.Part StatusObsoleteMemory TypeNon-VolatileMemory FormatFLASHTechnologyFLASH - NORMemory Size8Mb (1M x 8)Memory InterfaceSPIClock Frequency75 MHzWrite Cycle Time - Word, Page15ms, 5msVoltage - Supply2.7V ~ 3.6VOperating Temperature-40°C ~ 85°C (TA)Mounting TypeSurface MountPackage / Case8-VDFN Exposed PadSupplier Device Package8-VDFPN (6x5) (MLP8)Base Product NumberM25P80 M25P80-VMP6TG TR ManufacturerMicron is one of the world's leading providers of advanced semiconductor solutions.

Non-volatile memory doesn't require power to retain data. NOR and NAND use different logic gates -- the fundamental building block of digital circuits -- in each memory cell to map data. What's the difference between NOR and NAND?NOR and NAND flash memory are different by their architecture and purpose. NOR memory is used for storing code and execution. Allows quick random access to any location in memory array. NAND memory is used for data storage. What is serial NOR Flash memory?The industry standard Quad SPI (Serial Peripheral Interface) interface is simple to use and is supported by virtually all modern chipsets. NOR Flash is the ideal memory for code storage in embedded systems due to its fast random read performance.

The quiescent current of the MIC2954 increases only slightly in dropout, thus prolonging battery life, Key MIC2954 features include protection against reversed battery, fold-back current limiting, and automotive load dump protection (60V positive transient).   The MIC2954-07/08YM is an adjustable version that includes an error flag output that warns of a low output voltage, which is often due to failing batteries on the input. This may also be used as a power-on reset. A logic-compatible shutdown input is provided that enables the regulator to be switched on and off. This part may be pin-strapped for 5V output or programmed from 1.24V to 29V with the use of two external resistors.   The MIC2954 is available in two voltage tolerances, ±0.5% maximum and ±1% maximum. Both are guaranteed for junction temperatures from –40°C to +125°C.   MIC2954-02WS Related Video Instruction Video:Microchip's new LDO voltage-regulator family MIC2954-02WS Video Description: High-current, high-voltage and high-performance applications benefit from Microchip’s new LDO voltage-regulator family.   MIC2954-02WS CAD Models   Figure: PCB Symbol     Figure: Footprint     Figure: 3D Model   MIC2954-02WS Block Diagram   Figure: Block Diagram   MIC2954-02WS Features High Accuracy 5V, Ensured 250 mA OutputLow Quiescent CurrentLow Dropout VoltageExtremely Tight Load and Line RegulationVery Low Temperature CoefficientCurrent and Thermal LimitingInput Withstands –20V Reverse Battery and +60V Positive TransientsError Flag Warns of Output DropoutLogic-Controlled Electronic ShutdownOutput Programmable from 1.24V to 29V (MIC2954-07/-08)Available in TO-220-3 and Surface-Mount SOT-223 and SOIC-8 Packages   MIC2954-02WS Applications Battery-Powered EquipmentCellular TelephonesLaptop, Notebook, and Palmtop ComputersPCMCIA VCCand VPPRegulation/SwitchingBarcode ScannersAutomotive ElectronicsSMPS Post-Regulators/DC-DC ModulesVoltage ReferenceHigh-Efficiency Linear Power Supplies   MIC2954-02WS Datasheet You can download the datasheet from the link given below.

An LDO regulator is a linear regulator that can operate at a very low potential difference between the input and output voltage. A linear regulator is a type of power supply IC that can output a steady voltage from an input voltage and is used in a variety of electronic devices.   What is the difference between LDO and voltage regulator? Linear regulators use linear, non-switching techniques to regulate the voltage output from the power supply. That minimum amount is called the dropout voltage. A low-dropout or LDO regulator is a DC linear regulator which can regulate the output voltage even when the supply voltage is very close to the output voltage.   How does a LDO regulator work? A low-dropout regulator's (LDO) nature is to regulate a voltage by turning excess power into heat, making this integrated circuit a good fit for low-power or small VIN-to-VOUT differential applications.   Where is LDO regulator used? The special feature of an LDO is its ability to have a very low voltage drop across it when providing a regulated output voltage. This allows the LDO to be used in power critical battery applications where the battery voltage (input voltage) is close to the required regulated output voltage.   How do you test a LDO regulator? One test method is to apply an input voltage that is some number of millivolts below the nominal output voltage and then load the LDO with the test current. For example, 3.2 V is applied to a 3.3-V LDO and then the output voltage is measured.
