They are specified in compliance with JEDEC standard no. 7A. The 74HC/HCT173 are 4-bit parallel load registers with clock enable control, 3-state buffered outputs (Q0 to Q3) and master reset (MR). When the two data enable inputs (E1 and E2) are LOW, the data on the Dn inputs is loaded into the register QUICK REFERENCE DATA GND = 0 V; Tamb = 25 °C; tr = tf = 6 ns 74HC/HCT173 synchronously with the LOW-to-HIGH clock (CP) transition. When one or both En inputs are HIGH one set-up time prior to the LOW-to-HIGH clock transition, the register will retain the previous data. Data inputs and clock enable inputs are fully edge-triggered and must be stable only one set-up time prior to the LOW-……
