Instructions:

1. Supply Voltage:

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

2. Output Current:

   • The low-level output current (I_OL) should not exceed -32mA.
   • The high-level output current (I_OH) should not exceed 32mA.

3. Input Current:

   • The low-level input current (I_IL) should not exceed -1mA.
   • The high-level input current (I_IH) should not exceed 20μA.

4. Propagation Delay Time:

   • The propagation delay time (t_pd) from input to output is typically between 18ns and 36ns.

5. Power Dissipation:

   • The maximum power dissipation (P_D) should not exceed 1000mW to prevent overheating.

6. Operating Temperature:

   • The ambient temperature (T_A) should be maintained between -55°C and 125°C for reliable operation.

7. Storage Temperature:

   • The device can be stored at temperatures ranging from -65°C to 150°C.

8. Handling:

   • Handle the device with care to avoid static discharge, which can damage the internal components.
   • Use appropriate ESD protection measures during handling and installation.

9. Mounting:

   • Ensure proper mounting and soldering techniques to avoid mechanical stress on the device.
   • Follow the recommended PCB layout guidelines to ensure optimal performance and reliability.
