Instructions for Use:

1. Power Supply Connection:

   • Connect the V_CC pin to a power supply within the specified range (4.5V to 5.5V).
   • Ground all GND pins.

2. Input Signal Levels:

   • Ensure that input signals are within the valid logic levels:
     • Logic Low: Less than or equal to 0.8V.
     • Logic High: Greater than or equal to 2.0V.

3. Output Load Considerations:

   • For reliable operation, keep output current within limits:
     • Output Low: Can sink up to 16mA.
     • Output High: Can source up to 400μA.

4. Propagation Delay:

   • The propagation delay is typically 9ns under standard conditions (V_CC = 5V, T_A = 25°C).

5. Thermal Management:

   • Keep the device within the operating temperature range (-40°C to 85°C). Ensure adequate heat dissipation if operating near maximum power dissipation.

6. Handling Precautions:

   • Handle with care to avoid damage from electrostatic discharge (ESD). Use appropriate ESD protection measures.

7. Storage and Handling:

   • Store in a dry environment and handle according to manufacturer guidelines to prevent damage.

For detailed specifications and additional information, refer to the official datasheet provided by the manufacturer.
