Overview
The 74HCT574PW,118 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 series, which is compatible with TTL (Transistor-Transistor Logic) input levels. It features a clock (CP) and output enable (OE) inputs, making it suitable for a variety of digital logic applications. 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, which is beneficial for bus-oriented applications.
