MC74HC164A/D

MC74HC164A

8−Bit Serial−Input/Parallel−

Output Shift Register

High−Performance Silicon−Gate CMOS

The MC74HC164A is identical in pinout to the LS164. The device

inputs are compatible with standard CMOS outputs; with pullup

resistors, they are compatible with LSTTL outputs.

The MC74HC164A is an 8−bit, serial−input to parallel−output shift

register. Two serial data inputs, A1 and A2, are provided so that one

input may be used as a data enable. Data is entered on each rising edge

of the clock. The active−low asynchronous Reset overrides the Clock

and Serial Data inputs.
