Overview
The SN74LVC2G74DCTRG4, produced by Texas Instruments, is a single positive-edge-triggered D-type flip-flop with individual data (D), clock (CP), set (SD), and reset (RD) inputs, and complementary Q and Q outputs. This device is designed to operate over a wide supply voltage range from 1.65 V to 5.5 V, making it versatile for various applications. It features overvoltage tolerant inputs up to 5.5 V and supports live insertion, partial-power-down mode, and back-drive protection through its IOFF circuitry.
