The active-low asynchronous Reset overrides the Clock and Serial Data inputs. Data is entered on each rising edge of the clock. Two serial data inputs, A1 and A2, are provided so that one input may be used as a data enable. The IN74AC164 is an 8-bit, serial-input to parallel-output shift register. The device inputs are compatible with standard CMOS outputs with pullup resistors, they are compatible with LS/ALS outputs. 1 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.
