Description

The ’AC164 and ’ACT164 are 8-bit serial-in/parallel-out shift

registers with asynchronousreset that utilize Advanced

CMOS Logic technology. Datais shifted on the positive edge

of the clock (CP). A LOW on the Master Reset (MR) pin

resetsthe shift register and all outputsgo tothe LOWstate

regardlessoftheinput conditions. Two Serial Datainputs

(DS1 and DS2) are provided;either one can be used as a

Data Enable control.
