Instructions for Use:

1. Supply Voltage (V_CC):

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

2. Input Voltage Levels:

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

3. Output Voltage Levels:

   • When the output is low, the voltage should be between 0 V and 0.5 V.
   • When the output is high, the voltage should be between 2.4 V and V_CC - 0.1 V.

4. Current Ratings:

   • The maximum output sink current (I_OL) is 24 mA.
   • The maximum output source current (I_OH) is -1.6 mA.

5. Propagation Delay:

   • The typical propagation delay time is 19 ns at 5 V and 25掳C.

6. Power Consumption:

   • The typical power consumption is 100 mW at 5 V and 25掳C.

7. Operating Temperature:

   • Ensure the ambient temperature (T_A) is within the specified range for reliable operation.

8. Handling Precautions:

   • Handle the device with care to avoid static discharge, which can damage the internal circuits.
   • Follow proper soldering techniques to prevent thermal shock and mechanical stress.

9. Storage:

   • Store the device in a dry, cool place to prevent moisture damage.

10. Testing:

    • Before integrating the device into a circuit, test it under controlled conditions to ensure it meets the specified parameters.
