Description

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 CD74AC164 Serial Data inputs (DS1 and DS2) are provided; either one can be used as a Data Enable control.
