Overview
The SN74LVC2G74DCUT is a single positive-edge-triggered D-type flip-flop manufactured by Texas Instruments. This device is designed for operation over a wide voltage range of 1.65 V to 5.5 V, making it versatile for various applications. It features clear and preset inputs, allowing for the outputs to be set or reset regardless of the levels of the other inputs. The flip-flop is triggered on the positive-going edge of the clock pulse, ensuring reliable data transfer. The SN74LVC2G74DCUT is available in an 8-pin VSSOP (Very Thin Small Outline Package) and is part of the 74LVC series, known for its low power consumption and high performance.
