74HC164 Description

Short technical summary and product information.

The 74HC164 is a high-speed Si-gate CMOS 8-bit edge-triggered shift register with serial data entry and parallel outputs. It is pin compatible with Low power Schottky TTL (LSTTL) and specified in compliance with JEDEC standard no. 7A.

 

Data is entered serially through one of two gated inputs (DSA or DSB) and shifts to the right on each LOW-to-HIGH transition of the clock (CP) input. A LOW level on the master reset (MR) input clears the register asynchronously, forcing all outputs LOW.

 

This IC is suitable for applications requiring expansion of microcontroller output pins, such as driving LED displays, controlling multiple devices, and data storage. It operates over a wide temperature range of -40°C to +125°C and supports supply voltages from 2V to 6V.

 

Available in multiple package options including DIP, SOIC, SSOP, TSSOP, and DHVQFN, the 74HC164 offers flexibility for various PCB designs. Its CMOS technology ensures low power consumption and good noise immunity.
