FEATURES
GENERAL DESCRIPTION
The 74HC/HCT164 are high-speed Si-gate CMOS devices
and are pin compatible with low power Schottky TTL
(LSTTL). They are specified in compliance with JEDEC
standard no. 7A.
The 74HC/HCT164 are 8-bit edge-triggered shift registers
with serial data entry and an output from each of the eight
stages.

Both inputs must be connected together or an unused
input must be tied HIGH.

transition of the clock (CP) input and enters into Q

A LOW level on the master reset (MR) input overrides all
other inputs and clears the register asynchronously,
forcing all outputs LOW.
