Instructions for Use:

1. Supply Voltage (V_CC):

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

2. Input Voltage Levels:

   • For a valid low input, the voltage should be between 0V and 0.8V.
   • For a valid high input, the voltage should be between 2.0V and V_CC.

3. Output Voltage Levels:

   • When the output is low, the voltage should not exceed 0.5V under a load current of 16mA.
   • When the output is high, the voltage should be at least 2.7V under a load current of -0.4mA.

4. Current Ratings:

   • The input leakage current should be within -1.0mA to 0.1mA.
   • The output leakage current should be within -16mA to 16mA.

5. Propagation Delay:

   • The typical propagation delay time is 23ns, with a maximum of 39ns.

6. Power Dissipation:

   • The power dissipation per package should not exceed 100mW.

7. Temperature Range:

   • The operating temperature range is from -55°C to 125°C.

8. Handling Precautions:

   • Handle the device with care to avoid static discharge, which can damage the internal circuits.
   • Ensure proper grounding and use anti-static wrist straps when handling the device.

9. Mounting and Soldering:

   • Follow standard soldering practices to ensure reliable connections.
   • Avoid overheating during soldering, as it can damage the device.

10. Storage:

    • Store the device in a dry, cool place to prevent moisture damage.
    • Keep the device in its original packaging until ready for use.
