Features
Description
• Buffered Inputs
The ’HC164 and ’HCT164 are 8-bit serial-in parallel-out shift
registers with asynchronous reset. Data is shifted on the
positive edge of 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.
