Overview
The 74AHC574PW,118 is a high-speed Si-gate CMOS octal D-type flip-flop produced by Nexperia USA Inc. This component is part of the 74AHC logic family and is designed for bus-oriented applications. It features separate D-type inputs for each flip-flop and 3-state non-inverting outputs. The device is triggered by a positive edge clock and includes an output enable (OE) input that controls the output state without affecting the flip-flop state.
