TECHNICAL DATA
KK74HC164袗
8-Bit Serial-Input/Parallel-Output
Shift Register
High-Performance Silicon-Gate CMOS
The
KK74HC164A
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
KK74HC164A
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.
