74LVC374A Octal D-type flip-flop 5 V tolerant inputs/outputs positive-edge trigger 3-state Rev. 5 27 August 2021 Product data sheet 1. General description The 74LVC374A 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 can be driven from either 3.3 V or 5 V devices. This feature allows the use of these devices as translators in mixed 3.3 V and 5 V environments. Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times. This device is fully specified for partial power down applications using I . The I circuitry OFF OFF disables the output, preventing the potentially damaging backflow current through the device when it is powered down. 2.
