description

The CY74FCT2374T is a high-speed, low-power, octal D-type flip-flop featuring separate D-type inputs for each flip-flop. On-chip termination resistors at the outputs reduce system noise caused by reflections. The CY74FCT2374T can replace the CY74FCT374T to reduce noise in an existing design.
