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-it nput oparallel-output shift register. Two serial data inputs, A1 and A2, are provided so that May be used as a data enab le. Data is entered on each rising Edge of the clock. The activeone input low asynchronous Reset overrides the Clock and Serial Data inputs.
Features
Outputs Directly Interface to CMOS, NMOS, and TTL Operating Voltage Range: 2.0 to 6.0 V Low Input Current: 1.0 A High Noise Immunity Characteristic of CMOS Devices
