MC54HC164A - 8-Bit Serial Input / Parallel Output Shift Register
MOTOROLA SEMICONDUCTOR TECHNICAL DATA 8-Bit Serial-Input/ Parallel-Output Shift Register High Performance Silicon Gate CMOS The MC54/74HC164A 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 MC54/74HC164A 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
