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.
