Overview
The SN74LVC2G74DCTRE6 is a single positive-edge-triggered D-type flip-flop designed by Texas Instruments. It is part of the LVC (Low-Voltage CMOS) family, known for its low power consumption and high-speed operation. This device operates with a supply voltage range of 1.65V to 5.5V, making it suitable for interfacing with both 3.3V and 5V systems. The flip-flop features two independent units, each with individual data input, clock (CLK), set (SET), and reset (RESET) inputs, providing flexibility in various applications such as data storage, data transferring, frequency division, and counters.
