74AHC374; 74AHCT374

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

The 74AHC374; 74AHCT374 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 are overvoltage tolerant. The 74AHCT374 device features TTL compatible inputs that are overvoltage tolerant. This feature allows the use of these devices as translators in mixed voltage environments.
