Description
The 74HC164 is identical in pinout to the LS/ALS164. The Device inputs are compatible with standard CMOS outputs, with pullup resistors, they are compatible with LS/ALSTTL outputs.The 74HC164 is an 8-bit, serial-itnput oparallel-output shift register. Two serial data inputs, A1 and A2, are provided so that one input May be used as a data enab le. Data is entered on each rising Edge of the clock. The activelow asynchronous Reset overrides the Clock and Serial Data inputs.

FEATUREs
• Outputs DirectlyInterface to CMOS, NMOS, and TTL
• Operating Voltage Range: 2.0 to 6.0 V
• LowInput Current: 1.0µA
• High Noise Immunity Characteristic of CMOS Devices
