Overview
The MC74HCT595ADTR2G is a part of the MC74HCT595A series, a high-performance silicon-gate CMOS device produced by onsemi. This component integrates an 8-bit shift register and an 8-bit D-type latch with three-state parallel outputs. It is designed to accept serial data and provide both serial and parallel outputs. The shift register and latch have independent clock inputs, and the device includes an asynchronous reset for the shift register. The MC74HCT595ADTR2G is compatible with standard CMOS or TTL outputs and can directly interface with the SPI serial data port on CMOS MPUs and MCUs.
