SN74LV273APWG4

The SN74LV273APWG4 is a high-speed, low-voltage, octal D-type flip-flop from Texas Instruments, designed for use in digital circuits. This device is part of the 74LV family, which is known for its low-voltage operation and high-speed performance, making it suitable for a variety of applications in modern electronics.

Key Features:

1. Functionality: The SN74LV273APWG4 contains eight D-type flip-flops, which are used for data storage and transfer. Each flip-flop has a data input (D), a clock input (CLK), and an output (Q). The flip-flops are edge-triggered, meaning they capture the input data on the rising edge of the clock signal.

2. Voltage Range: It operates within a supply voltage range of 2.0V to 5.5V, making it compatible with both low-voltage and standard logic levels. This flexibility allows it to be used in battery-powered devices and other low-power applications.

3. Speed: The device is designed for high-speed operation, with a maximum clock frequency of up to 100 MHz at 5V, ensuring quick data processing and transfer.

4. Output Drive Capability: The outputs can drive up to 24 mA, allowing for direct connection to other logic devices or loads without the need for additional buffering.

5. Package Type: The SN74LV273APWG4 is available in a TSSOP (Thin Shrink Small Outline Package) with a 20-pin configuration. This compact package is ideal for space-constrained applications, providing a small footprint while maintaining high performance.

6. Power Consumption: The device features low static and dynamic power consumption, which is essential for energy-efficient designs, particularly in portable and battery-operated devices.

7. Input/Output Logic Levels: The inputs are compatible with standard TTL logic levels, ensuring seamless integration with other components in a digital system.

8. Asynchronous Set and Reset: The flip-flops include asynchronous set (PRE) and reset (CLR) inputs, allowing for immediate control of the output states regardless of the clock signal. This feature is useful for initializing the flip-flops to a known state.

9. Temperature Range: The device is rated for operation over a wide temperature range, typically from -40°C to +125°C, making it suitable for industrial and automotive applications.

Applications:

The SN74LV273APWG4 is commonly used in various applications, including:

• Data storage and transfer in digital circuits
• Shift registers and data buffers
• State machines and control logic
• Timing applications in synchronous systems
• Microcontroller interfacing

Conclusion:

The SN74LV273APWG4 from Texas Instruments is a versatile and reliable octal D-type flip-flop that combines high-speed performance with low-voltage operation. Its features make it an excellent choice for a wide range of digital applications, particularly where space and power efficiency are critical.
