Overview
The 74HC574PW-Q100 is an 8-bit positive-edge triggered D-type flip-flop with 3-state outputs, manufactured by Nexperia USA Inc. This device is part of the 74HC series and is designed to meet the stringent requirements of automotive and industrial applications. 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.
