Instructions for Use:

1. Supply Voltage (V_CC):

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

2. Output Voltage Levels:

   • The output voltage high (V_OH) should be at least 2.4V when the output is driving a load of -4mA.
   • The output voltage low (V_OL) should be no more than 0.5V when the output is driving a load of 16mA.

3. Input Voltage Levels:

   • The input voltage high (V_IH) should be at least 2.0V to ensure a high logic level.
   • The input voltage low (V_IL) should be no more than 1.5V to ensure a low logic level.

4. Input Current:

   • The input current (I_IH and I_IL) should be within the specified range to avoid excessive power consumption or damage.

5. Propagation Delay Time:

   • The propagation delay time (t_pd) is the time it takes for the output to change state after the input changes. It should be within 10 to 30 nanoseconds under the specified conditions.

6. Power Dissipation:

   • The maximum power dissipation (P_D) should not exceed 100mW to prevent overheating and potential failure.

7. Operating Temperature:

   • The device is designed to operate within the temperature range of -40掳C to 85掳C. Ensure that the ambient temperature does not exceed these limits.

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. Storage:

   • Store the device in a dry, cool place to prevent moisture damage and ensure long-term reliability.

10. Mounting:

    • Follow the recommended PCB layout and mounting guidelines to ensure proper electrical performance and thermal management.
