4-Bit Data Register with Clock Enable and Asynchronous Clear
When clock enable (CE) is High, and asynchronous clear (CLR) is Low, the data on the four data inputs (D3 – D0) of FD4CE is transferred to the corresponding data outputs (Q3 – Q0) during the Lowto- High clock (C) transition. When CLR is High, it overrides all other inputs and resets the data outputs (Q3 – Q0) Low. When CE is Low, clock transitions are ignored.
