Overview
The MC74HC595ADR, produced by onsemi, is an 8-bit serial-input/serial or parallel-output shift register with latched 3-state outputs. This device combines an 8-bit shift register and an 8-bit D-type latch, allowing for serial data input and both serial and parallel data output. It is designed for high-performance applications and is compatible with Standard CMOS and TTL outputs.
The device features independent clock inputs for the shift register and the latch, as well as an asynchronous reset for the shift register. It is suitable for a wide range of applications due to its low power dissipation and high noise immunity.
