Overview
The MC74HC595ADH is a high-performance silicon-gate CMOS integrated circuit produced by ON Semiconductor. It consists of an 8-bit serial-input/serial or parallel-output shift register and an 8-bit D-type latch with three-state parallel outputs. This device is designed to accept serial data and provide both serial and parallel outputs, making it versatile for various applications. The shift register and latch have independent clock inputs, and the device includes an asynchronous reset for the shift register.
