SN74LVT125NSR

The SN74LVT125NSR is a quad buffer/driver with 3-state outputs, designed by Texas Instruments. It is part of the LVT (Low Voltage TTL) family, which is known for its high-speed performance and low power consumption. This device is particularly useful in applications where signal buffering and driving capabilities are required.

Key Features:

1. Quad Buffer/Driver Configuration: The SN74LVT125NSR contains four independent buffer/driver circuits, allowing it to handle multiple signals simultaneously. Each buffer can be used to drive a load or to isolate different parts of a circuit.

2. 3-State Outputs: Each output can be placed in a high-impedance state, which is essential for bus-oriented applications where multiple devices share the same output line. This feature allows for easy interfacing with other devices without causing signal contention.

3. Voltage Range: The device operates with a supply voltage range of 1.65V to 5.5V, making it compatible with a variety of logic levels. This flexibility allows it to be used in both low-voltage and standard TTL applications.

4. High-Speed Operation: The SN74LVT125NSR is designed for high-speed performance, with propagation delays typically around 3.5 ns at 3.3V. This makes it suitable for high-frequency applications where quick signal transitions are necessary.

5. Low Power Consumption: The device features low static and dynamic power consumption, which is beneficial for battery-operated devices and applications where power efficiency is critical.

6. Input/Output Compatibility: The inputs are compatible with standard TTL levels, and the outputs can drive TTL loads, making it versatile for interfacing with various components in a digital circuit.

7. Thermal Characteristics: The SN74LVT125NSR is available in a small-outline package (SOIC), which helps in reducing the overall footprint on a PCB. It is designed to operate over a wide temperature range, typically from -40°C to +125°C, ensuring reliability in various environmental conditions.

8. Pin Configuration: The device typically features a 20-pin configuration, with each buffer having its own input and output pins, along with enable pins that control the 3-state functionality.

Applications:

The SN74LVT125NSR is commonly used in applications such as:

• Data buffering in communication systems
