Overview
The MC74HC595ADT, produced by onsemi, is a high-performance silicon-gate CMOS device that integrates an 8-bit shift register and an 8-bit D-type latch with three-state parallel outputs. This component is designed to accept serial data and provide both serial and parallel outputs, making it versatile for various digital circuit 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 Standard CMOS outputs and, with pull-up resistors, can also interface with TTL outputs.
