DESCRIPTION
The 74F173 is a high speed 4- bit parallel load register with clock enable control, 3- state buffered outputs, and master reset (MR). When the two clock enable (E0 and E1) inputs are low, the data on the D inputs is loaded into the register simultaneously with low- to- high clock (CP) transition. When one or both enable inputs are high one setup time before the low- to- high clock transition, the register retains the previous data.
TYPE 74F173 TYPICAL fmax 125MHz
Data inputs and clock enable inputs are fully edge- triggered and must be stable only one setup time before the low- to- high clock transition. The master reset (MR) is an active- high asynchronous input. When the MR is high, all four flip- flops are...
