Overview
The MC74HC595ANG, produced by onsemi, is a high-performance silicon-gate CMOS integrated circuit. It consists of an 8-bit shift register and an 8-bit D-type latch with three-state parallel outputs. The device accepts serial data and provides both serial and parallel outputs. The shift register and latch have independent clock inputs, and there is an asynchronous reset for the shift register. This component is designed to directly interface with the SPI serial data port on CMOS MPUs and MCUs, making it versatile for various applications.
