Overview
The 74AHC574PW,112 is an octal D-type flip-flop with 3-state outputs, produced by Nexperia (previously part of NXP USA Inc.). This high-speed Si-gate CMOS device is designed for bus-oriented applications and features a wide supply voltage range, making it versatile for various electronic designs. The device includes a clock (CP) and output enable (OE) inputs, allowing for the storage of the state of individual D-inputs on the LOW-to-HIGH clock transition. The outputs can be set to a high-impedance OFF-state when the OE input is HIGH, without affecting the state of the flip-flops.
