TECHNICAL DATA IN74AC164 8-Bit Serial-Input/Parallel-Output Shift register High-Speed Silicon-Gate CMOS The IN74AC164 is identical in pinout to the LS/ALS164, HC/HCT164.
The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALS outputs.
The IN74AC164 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.
