74AHC374D

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

The 74AHC374; 74AHCT374 is a high-speed Si-gate CMOS device and is pin compatible with Low-power Schottky TTL (LSTTL). It is specified in compliance with JEDEC standard No. 7-A.

The 74AHC374; 74AHCT374 comprises eight D-type flip-flops featuring separate D-type inputs for each flip-flop and 3-state outputs for bus oriented applications. A clock input (CP) and an output 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 for the LOW-to-HIGH CP transition.

When OE is LOW the content of the eight flip-flops is available at the outputs. When 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.
