Overview
The 74LVC374APW is an octal positive-edge triggered D-type flip-flop with 3-state outputs, manufactured by Nexperia USA Inc. This device is designed to operate in a wide range of applications, particularly in mixed 3.3 V and 5 V environments. It features a clock (CP) and output enable (OE) inputs, allowing for flexible control over the output states. The flip-flops store the state of their individual D-inputs on the LOW-to-HIGH clock transition, and a HIGH on the OE input causes the outputs to assume a high-impedance OFF-state without affecting the state of the flip-flops.
The device is characterized by its CMOS low power dissipation, direct interface with TTL levels, and overvoltage tolerant inputs up to 5.5 V. It also includes IOFF circuitry for partial power-down mode operation and Schmitt-trigger action at all inputs, making it tolerant of slower input rise and fall times.
