Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage (V_CC) is within the specified range of 4.75V to 5.25V to avoid damage to the device.

2. Input Levels:

   • For valid low input, ensure the voltage is between 0V and 0.8V.
   • For valid high input, ensure the voltage is between 2.0V and V_CC.

3. Output Levels:

   • When the output is low, the voltage should be between 0.25V and 0.5V under a load of 16 mA.
   • When the output is high, the voltage should be between 2.7V and V_CC under a load of -0.4 mA.

4. Propagation Delay:

   • The typical propagation delay time is 33 nanoseconds at room temperature (25°C) and a supply voltage of 5V.

5. Power Dissipation:

   • Do not exceed the maximum power dissipation of 500 mW to prevent overheating and potential damage.

6. Temperature Ranges:

   • The operating temperature range is from -40°C to 85°C.
   • The storage temperature range is from -65°C to 150°C.

7. Handling:

   • Handle the device with care to avoid static discharge, which can damage sensitive components.
   • Use appropriate anti-static measures when handling and storing the device.

8. Mounting:

   • Ensure proper mounting and soldering techniques to avoid mechanical stress and ensure reliable connections.

9. Testing:

   • Before integrating the device into a circuit, test it in a controlled environment to verify its functionality and performance.
