74HC595N Description
The 74HC595N contains an 8-bit, serial-in, parallel-out shift register that feeds an 8-bit D-type latch with parallel 3-state outputs. Separate clocks are provided for both the shift register and latch. The shift register has a direct overriding clear input, serial input, and serial outputs for cascading. The 74HC595N also has an asynchronous reset for the shift register.

Frequently Asked Questions
1.What is 74HC595N?
The 74HC595N is a shift register that works on Serial IN Parallel OUT protocol. It receives data serially from the microcontroller and then sends out this data through parallel pins. We can increase our output pins by 8 using the single chip. We can also connect more than 1 shift register in parallel.
2.What does a shift register do?
A shift register is a type of digital circuit using a cascade of flip flops where the output of one flip-flop is connected to the input of the next. They share a single clock signal, which causes the data stored in the system to shift from one location to the next.
