Overview
The 74HC595DR2G, produced by onsemi, is a high-performance silicon-gate CMOS integrated circuit that functions as an 8-bit serial-input/serial or parallel-output shift register with latched 3-state outputs. This device combines an 8-bit shift register and an 8-bit D-type latch, allowing it to accept serial data and provide both serial and parallel outputs. It is designed to interface directly with the SPI serial data port on CMOS microprocessors and microcontrollers.
