Instructions for Use:

1. Supply Voltage:

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

2. Input Levels:

   • Input voltages should be within the specified high (V_IH) and low (V_IL) levels to ensure proper operation.

3. Output Levels:

   • The output voltages should be monitored to ensure they remain within the specified high (V_OH) and low (V_OL) levels.

4. Current Limits:

   • Do not exceed the maximum input and output current ratings to prevent damage to the device.

5. Propagation Delay:

   • The propagation delay time is crucial for timing considerations in your circuit. Ensure that your design accounts for this delay.

6. Power Consumption:

   • Monitor the total power consumption to ensure it does not exceed the maximum rating.

7. Operating Temperature:

   • The device is typically rated for operation over a temperature range from -40°C to 85°C. Ensure the operating environment stays within these limits.

8. Storage and Handling:

   • Store the device in a dry, static-free environment to prevent damage.
   • Handle with care to avoid mechanical stress on the pins and package.

9. Soldering:

   • Use appropriate soldering techniques and temperatures to avoid thermal damage to the device.

10. Testing:

    • Before integrating the device into a larger system, test it individually to ensure it meets all specifications.
