Instructions for Use

1. Power Supply: Ensure the supply voltage (VCC) is within the range of 2.0V to 6.0V. The device operates optimally at 5V.

2. Input Signals:

   • For a valid low input signal, ensure the voltage does not exceed 0.8V.
   • For a valid high input signal, the voltage should be at least 2.0V.

3. Output Signals:

   • When sourcing current (output high), the output voltage should be at least 4.5V with a load current of 4.0mA.
   • When sinking current (output low), the output voltage should not exceed 0.1V with a load current of -4.0mA.

4. Propagation Delay: The typical propagation delay time (tpd) under standard conditions (VCC = 5V, TA = 25°C) is 12ns.

5. Thermal Considerations: The maximum power dissipation is 100mW. Ensure adequate heat dissipation if operating near this limit.

6. Temperature Range: The device is rated for operation from -40°C to 85°C ambient temperature.

7. Handling Precautions: This device is sensitive to electrostatic discharge (ESD). Handle with appropriate ESD precautions.

8. Mounting and Layout: Follow standard guidelines for mounting and PCB layout to ensure reliable operation and minimize noise interference.
