Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage (Vcc) is within the specified range of 4.75V to 5.25V.
   • Connect Vcc to the positive power supply and GND to the ground.

2. Input Levels:

   • Input voltages should be within the specified ranges for high (VIH) and low (VIL) levels to ensure proper logic operation.

3. Output Levels:

   • The output high (VOH) and low (VOL) levels must meet the specified conditions to drive subsequent stages or devices.

4. Propagation Delay:

   • The propagation delay time (tpd) is critical for timing considerations in digital circuits. It should be within the specified range to avoid timing issues.

5. Power Dissipation:

   • Monitor the power dissipation (PD) to ensure it does not exceed the maximum rating, especially at higher frequencies.

6. Temperature Range:

   • The device can operate over a wide temperature range from -55°C to 125°C. Ensure the operating environment is within these limits.

7. Handling:

   • Handle the device with care to avoid static damage. Use proper ESD protection measures during handling and installation.

8. Mounting:

   • Follow standard PCB mounting guidelines to ensure reliable performance and thermal management.

9. Testing:

   • Perform initial testing under controlled conditions to verify proper functionality before deploying in a larger system.
