• Buffered Inputs
The ’AC164 and ’ACT164 are 8-bit serial-in/parallel-out shift
registers with asynchronous reset that utilize Advanced
CMOS Logic technology. Data is shifted on the positive edge
of the clock (CP). A LOW on the Master Reset (MR) pin
resets the shift register and all outputs go to the LOW state
regardless of the input conditions. Two Serial Data inputs
(DS1 and DS2) are provided; either one can be used as a
Data Enable control.
