SN74LVC1G74DCTR

The SN74LVC1G74DCTR is a single D-type flip-flop from Texas Instruments, designed for low-voltage applications. It is part of the LVC family, which stands for Low-Voltage CMOS, and is optimized for operation in a wide range of voltage levels, typically from 1.65V to 5.5V. This makes it suitable for interfacing with both low-voltage and standard logic levels.

Key Features:

1. Functionality: The SN74LVC1G74DCTR is a D flip-flop, which means it captures the value of the D (data) input at a specific edge of the clock signal (either rising or falling, depending on the configuration) and holds that value until the next clock edge. This makes it useful for data storage, synchronization, and state retention in digital circuits.

2. Input and Output: The device has a single D input, a clock input (CLK), a clear input (CLR), and a Q output. The clear input allows for asynchronous resetting of the flip-flop, setting the Q output to a low state regardless of the clock signal.

3. Propagation Delay: The SN74LVC1G74DCTR features low propagation delays, typically around 3.5 ns at 3.3V, which allows for high-speed operation in digital circuits.

4. Power Consumption: With its low-voltage operation, the device is designed to consume minimal power, making it ideal for battery-powered applications and energy-efficient designs.

5. Temperature Range: The device operates over a wide temperature range, typically from -40°C to +125°C, ensuring reliability in various environmental conditions.

6. Package Type: The SN74LVC1G74DCTR is available in a small SOT-23 package, which is compact and suitable for space-constrained applications. The SOT-23 package typically has 5 pins, making it easy to integrate into printed circuit boards (PCBs).

7. Logic Levels: The device is compatible with various logic levels, allowing it to interface seamlessly with other components in a digital system. It can accept input signals as low as 1.65V and can drive outputs up to 5.5V.

8. Applications: Common applications for the SN74LVC1G74DCTR include data storage, frequency division, state machines, and other digital logic applications where reliable data storage and transfer are required.

Summary:

The SN74LVC1G74DCTR is a versatile and efficient D flip-flop that provides reliable performance in low-voltage digital circuits. Its combination of low power consumption, wide operating voltage range, and compact packaging makes it an excellent choice for modern electronic designs, particularly in portable and battery-operated devices.
