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 condi- tions. Two Serial Data inputs (DS1 and DS2) are provided, either one can be used as a Data Enable control. Pinout CD74HC164, CD74HCT164 (PDIP, SOIC) TOP VIEW Ordering Information PART NUMBER TEMP.
