SL74HC164
8-Bit Serial-Input/Parallel-Output
Shift Register
High-Performance Silicon-Gate CMOS
The SL74HC164 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 SL74HC164 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. Data is entered on each rising edge
of the clock. The active-low asynchronous Reset overrides theClock
and Serial Data inputs.
• Outputs Directly Interface to CMOS, NMOS, and TTL
• Operating Voltage Range: 2.0 to 6.0 V
• Low Input Current: 1.0 µA
• High Noise Immunity Characteristic of CMOS Devices
