Overview
The 74LVC374APW-Q100J is an octal positive-edge triggered D-type flip-flop with 3-state outputs, manufactured by Nexperia USA Inc. This device is designed for use in a wide range of applications requiring high-speed data storage and transfer. It features a clock (CP) and output enable (OE) inputs, allowing for precise control over data storage and 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 flip-flop states.
The device is compatible with both 3.3 V and 5 V logic levels, making it suitable for mixed voltage environments. It also includes Schmitt-trigger action at all inputs, enhancing tolerance to slower input rise and fall times. Additionally, the 74LVC374APW-Q100J is fully specified for partial power-down applications using IOFF circuitry, which prevents backflow current when the device is powered down.
