Overview
The 74HCT574D,652, manufactured by NXP Semiconductors, is an 8-bit positive-edge triggered D-type flip-flop with 3-state outputs. This integrated circuit is part of the 74HCT family, which utilizes high-speed Si-gate CMOS technology. The device is designed for bus-oriented applications and features a clock (CP) and output enable (OE) inputs. 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, without affecting the state of the flip-flops.
