Data is entered SF00717 through one of two inputs (Dsa, Dsb) either input can be used as an active High enable for data entry through the other input. Both inputs must be connected together or an unused input must be tied High. TYPICAL SUPPLY TYPE TYPICAL f max CURRENT (TOTAL) Data shifts one place to the right on each Low-to-High transition of the clock (CP) input, and enters into Q0 the logical AND of the two 74F164 100MHz 33 mA data inputs (Dsa, Dsb) that existed one setup time before the rising edge. A Low level on the Master Reset (MR) input overrides all other inputs and clears the register asynchronously, forcing all outputs Low.
