Overview
The 74HC574PW-Q100118 is an 8-bit positive-edge triggered D-type flip-flop with 3-state outputs, manufactured by NXP USA Inc. This device is part of the 74HC series and is designed for use in a variety of digital logic applications. It features a clock (CP) and output enable (OE) inputs, allowing the flip-flops to store the state of their individual D-inputs on the LOW-to-HIGH clock transition. The outputs can be set to a high-impedance OFF-state by a HIGH on the OE input, without affecting the state of the flip-flops. This component is qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1), making it suitable for automotive applications.
