Overview
The SN74LVC2G74DCUTE4 is a single positive-edge-triggered D-type flip-flop produced 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 individual data (D), clock (CP), set (SD), and reset (RD) inputs, along with complementary Q and Q outputs. The flip-flop is triggered on the positive edge of the clock pulse, and data at the D input is stored and appears at the Q output when the setup and hold time requirements are met.
