Quadruple D-type register with 3-state outputs

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.
