’F378 consists of six edge-triggered D-type flip-flops with individual D inputs and Q inputs 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 Truth Table Inputs E H L L CP L L
