Product Overview
The SN74LVC1G74DCU is a single positive-edge-triggered D-type flip-flop with clear and preset from Texas Instruments. Designed for operation from 1.65V to 5.5V, this device features balanced outputs, over-voltage tolerant inputs, partial power-down mode (Ioff), and very high speed with propagation delays as low as 5.9ns. The DCU variant comes in the VSSOP-8 NanoFree package, making it ideal for space-constrained applications including servers, LED displays, network switches, telecom infrastructure, and motor drivers.
