Overview
The 74HCT574PW-Q100,11 from Nexperia USA Inc. is an 8-bit positive-edge triggered D-type flip-flop with 3-state outputs. This device is part of the 74HCT family and is designed for use in a variety of applications, including automotive, industrial, and consumer electronics. 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 state of the flip-flops.
