Overview
The 74HC374DB,118 is an octal D-type flip-flop with positive edge-trigger and 3-state outputs, manufactured by Nexperia USA Inc. This device is part of the 74HC and 74HCT series, known for their low power dissipation and high noise immunity. The flip-flops store the state of their individual D-inputs on the LOW-to-HIGH clock transition, and the outputs can be set to a high-impedance OFF-state using the output enable (OE) input. This component is widely used in digital circuits for data storage and transfer.
