DESCRIPTION
The HEF4076B is a quadruple edge-triggered D-type flip-flop with four data inputs (D0to D3), two active LOW data enable inputs (ED0and ED1), a common clock input (CP), four 3-state outputs (O0to O3), two active LOW output enable inputs (EO0and EO1), and an overriding asynchronous master reset input (MR).
Information on D
0
to D3is stored in the four flip-flops on the LOW to HIGH transition of CP if both ED0and ED1are LOW. A HIGH on either ED0or ED1prevents the flip-flops from changing on the LOW to HIGH transition of CP, independent of the information on D0to D3. When both EO0and EO1are LOW, the contents of the four flip-flops are available at O0to O3. A HIGH on either EO0or EO1forces O0to O3into the high impedance OFF-state. A HIGH on MR resets all four flip-flops, independent of all other input conditions.
