The IC component SN74LS595N is a shift register and storage register integrated circuit. It has several key features that make it useful in various digital applications. Let's explore its overview and key features below:
1. Overview:
- The SN74LS595N is a 8-bit serial-in, parallel-out (SIPO) shift register.
- It consists of an 8-bit Shift Register and an 8-bit storage register.
- The shift register is controlled by an external clock signal, allowing serial data to be shifted in and out.
- The parallel outputs of the storage register can be latched or updated at any desired clock cycle.
- It operates with a wide voltage range of 2V to 6V, making it compatible with both TTL and CMOS logic levels.
2. Serial-In, Parallel-Out (SIPO) Shift Register:
- The SN74LS595N can receive data serially, one bit at a time.
- It features a serial data input (DS) pin, where data is inputted bit by bit.
- The incoming bits are sequentially shifted into the shift register on each clock pulse.
- As a result, the data shifts from the rightmost bit to the leftmost bit.
3. Latch and Output Enable Functionality:
- The SN74LS595N has two control pins, OE (Output Enable) and ST_CP (Store Clock Pulse)
