Description

The SN74LVC2G74DCTR is a dual positive-edge-triggered D-type flip-flop integrated circuit from Texas Instruments. It is designed for low-voltage applications, operating with a supply voltage range of 1.65 V to 5.5 V. This IC is suitable for a variety of digital logic applications due to its low power consumption and high-speed operation. Each flip-flop has independent data (D), clock (CLK), preset (PRE), and clear (CLR) inputs, along with complementary outputs (Q and Q̅).
Key features include a Schmitt-trigger action on the CLK input, which provides better noise immunity and a high input impedance. The SN74LVC2G74DCTR also offers partial power-down protection, ensuring that the outputs remain in a known state when the device is powered down. Its compact design, available in a small SOT-23 package, makes it ideal for space-constrained applications. This IC is commonly used in data storage, data transfer, and counter or frequency divider applications in various electronic devices.
