Instructions for Use:

1. Power Supply: Ensure the supply voltage (Vcc) is within the specified range of 4.5V to 5.5V to avoid damage to the device.
2. Input Levels: Inputs should be kept within valid logic levels. For a high input, ensure the voltage is above 2.0V and below 5.5V. For a low input, keep it between 0V and 0.8V.
3. Output Levels: When sourcing current, the output can provide up to 0.4mA while maintaining a high level above 2.7V. When sinking current, it can handle up to 16mA while keeping the output voltage below 0.5V.
4. Propagation Delay: Expect a typical propagation delay of 15ns under standard operating conditions.
5. Power Handling: Do not exceed the maximum power dissipation of 600mW continuously to prevent overheating or failure.
6. Handling Precautions: This device is sensitive to electrostatic discharge (ESD). Use appropriate ESD protection when handling.
7. Mounting: Ensure proper mounting and soldering techniques to maintain electrical characteristics and reliability.

For detailed specifications and advanced applications, refer to the manufacturer's datasheet.
