74ALVC374BQ: Octal D-type flip-flop; positive-edge trigger; 3-state

The 74ALVC374 is an octal D-type flip-flop featuring separate D-type inputs for each flip-flop and 3-state outputs for bus-oriented applications. A clock input (CP) and an outputs enable input (OE) are common to all flip-flops.

The eight flip-flops will store the state of their individual D-inputs that meet the set-up and hold times requirements on the LOW to HIGH CP transition.

When pin OE is LOW, the contents of the eight flip-flops is available at the outputs. When pin OE is HIGH, the outputs go to the high-impedance OFF-state. Operation of the OE input does not affect the state of the flip-flops.

The 74ALVC374 is functionally identical to the 74ALVC574, but has a different pin arrangement.
