General description
The 74LVC374A 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.
Inputs can be driven from either 3.3 V or 5 V devices. When disabled, up to 5.5 V can be
applied to the outputs. These features allow the use of these devices as translators in mixed 3.3 V and 5 V applications.
The 74LVC374A is functionally identical to the 74LVC574A, but has a different pin arrangement.
