Overview
The MC74HC595ADTG, produced by onsemi, is a high-performance silicon-gate CMOS integrated circuit. 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. It is compatible with the SPI serial data port on CMOS MPUs and MCUs, and its inputs are compatible with standard CMOS outputs and TTL outputs with pull-up resistors.
