Overview
The SN74LVC2G74DCUTG4 is a single positive-edge-triggered D-type flip-flop with clear and preset inputs, manufactured by Texas Instruments. This device is part of the 74LVC series, known for its low-voltage CMOS logic family. It operates over a wide voltage range from 1.65 V to 5.5 V, making it versatile for various applications. The flip-flop is designed to transfer data from the D input to the outputs on the positive-going edge of the clock pulse, and it includes preset and clear inputs for setting or resetting the outputs regardless of the clock state.
