1. General description

The 74HC374; 74HCT374 is an octal positive-edge triggered D-type flip-flop with 3-state outputs.

The device features a clock (CP) and output enable (OE) inputs. The flip-flops will store the state

of their individual D-inputs that meet the set-up and hold time requirements on the LOW-to-HIGH

clock (CP) transition. A HIGH on OE causes the outputs to assume a high-impedance OFF-state.

Operation of the OE input does not affect the state of the flip-flops. Inputs also include clamp

diodes, this enables the use of current limiting resistors to interface inputs to voltages in excess of

VCC.
