^{The 'HC164 and 'HCT164 are 8-bit serial-in parallel-out shiftregisters with asynchronous reset. Data is shifted on thepositive edge of Clock (CP). A LOW on the Master Reset(MR) pin resets the shift register and all outputs go to theLOW state regardless of the input conditions. Two SerialData inputs (DS1 and DS2) are provided, either one can beused as a Data Enable control.}
