ESTEK74HC164

8-bit serial-in/parallel-out shift register

Estek Electronics Co. Ltd 

74HC164

Description

The 74HC164 is identical in pinout to the LS/ALS164. The Device inputs are compatible with

standard CMOS outputs, with pullup resistors, they are compatible with LS/ALSTTL outputs. The 74HC164 is

an 8-bit, serial-itnput oparallel-output shift register. Two serial data inputs, A1 and A2, are provided so that

one input May be used as a data enab le. Data is entered on each rising Edge of the clock. The active-

low async-

hronous Reset overrides the Clock and Serial Data inputs.

Features

•Outputs Directly Interface to CMOS, NMOS, and TTL

•Operating Voltage Range: 2.0 to 6.0 V

•Low Input Current: 1.0 µA

•High Noise Immunity Characteristic of CMOS Devices
