Overview
The Nexperia 74HC574PW,118 is an 8-bit positive-edge triggered D-type flip-flop integrated circuit (IC) with 3-state outputs. This device is part of the 74HC logic family and is designed for use in a wide range of digital circuits. 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. This IC is suitable for applications requiring low power consumption, high noise immunity, and reliable operation across various temperature ranges.
