74HC595 Serial to Parallel Shifting IC

[Logic Gates IC] DESCRIPTION:- The 74HC595N is a simple 8-bit shift register IC. Simply put, this shift register is a device that allows additional inputs or outputs to be added to a microcontroller by converting data between parallel and serial formats. Your chosen microprocessor is able to communicate with The 74HC595N using serial information then gathers or outputs information in a parallel (multi-pin) format. Essentially it takes 8 bits from the serial input and then outputs them to 8 pins. This small DIP packaged IC contains an 8-bit, serial-in-parallel-out shift register that feeds an 8-bit D-type storage register with parallel 3-state outputs.   Pin Configuration:- Pin Number Pin Name Description 1,2,3,4,5,6,7 Output Pins (Q1 to Q7) The 74hc595 has 8 output pins out of which 7 are these pins. They can be controlled serially 8 Ground Connected to the Ground of the circuit 9 (Q7) Serial Output This pin is used to connect more than one 74hc595 as cascading 10 (MR) Master Reset Resets all outputs as low. Must be held high for normal operation 11 (SH_CP) Clock This is the clock pin to which the clock signal has to be provided from MCU/MPU 12 (ST_CP) Latch The Latch pin is used to update the data to the output pins. It is active high 13 (OE) Output Enable The Output Enable is used to turn off the outputs. Must be held low for normal operation 14 (DS) Serial Data This is the pin to which data is sent, based on which the 8 outputs are controlled 15 (Q0) Output The first output pin. 16 Vcc This pin powers the IC, typically +5V is used.   Features :- 8-bit, Serial In – Parallel out Shift register Operating Voltage: 2V to 6V Power Consumption: 80uA Output source/sink current: 35mA Output Voltage is equal to Operating voltage Minimum high-level Input Voltage: 3.15V @(Vcc=4.5V) Maximum low-level Input Voltage: 1.35V @(Vcc=4.5V) Can be easily cascaded with more IC to get more outputs Maximum Clock Frequency: 25Mhz @4.5V Available in 16-pin PDIP, GDIP, PDSO packages Where to Use 74HC595 IC:- The 74HC595 is an 8-bit Serial In – Parallel Out Shift Register, i.e. it can receive (input) data serially and control 8 output pins in parallel. This comes in very handy where do not have enough GPIO pins on our MCU/MPU to control the required number of outputs. It is often used in projects where relatively a large number of LED's has to be controlled through the Microcontroller. It can also be used to interface LCD screen since they can acts as the data bit for the LCD displays. It can also be used to control 5V loads like relays through a 3.3V microcontroller since the high-level voltage is only 3.15. So if you are looking for an IC to save on your GPIO pins on the Microcontroller then this IC might be the right choice for you. How to Use a 74HC595 IC:- The 74HC595 shift register is commonly used with microcontrollers or microprocessors to expand the GIPO functionalities. It requires only 3 pins connected to the MCU, which are Clock, Data and Latch. It has a wide operating voltage from 2V to 6V. An application circuit of the IC is shown below: Package Includes:- 1 x 74HC595 IC
