Overview
The 74HC574DB,118 is an 8-bit positive-edge triggered D-type flip-flop integrated circuit produced by Nexperia USA Inc. This device is part of the 74HC series and features 3-state outputs, making it suitable for bus-oriented applications. The flip-flop stores the state of its individual D-inputs on the LOW-to-HIGH clock transition and includes a clock (CP) and output enable (OE) inputs. The OE input allows the outputs to assume a high-impedance OFF-state without affecting the state of the flip-flops.
