Overview
The 74HC574PW,112 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 for a wide range of applications requiring data storage and transfer. The flip-flop stores the state of its individual D-inputs on the LOW-to-HIGH clock (CP) transition and features an output enable (OE) input that allows the outputs to be set to a high-impedance OFF-state when OE is HIGH.
