2 / 7 page MC74AC378 MC74ACT378 5-2 FACT DATA FUNCTIONAL DESCRIPTION The MC74AC378/74ACT378 consists of six edge- triggered D-type flip-flops with individual D inputs and Q outputs. The Clock (CP) and Enable (E) inputs are common to all flip-flops. When the E input is LOW, new data is entered into the register on the LOW-to-HIGH transition of the CP input. When the E input is HIGH, the register will retain the present data independent of the CP input. Please note that this diagram is provided only for the understanding of logic operations and should not be used to estimate propagation delays.
