Instructions for Use:

  1. Supply Voltage:

    • Ensure the supply voltage (VCC) is within the range of 2.0V to 6.0V.
    • Connect the ground (GND) pin to a stable reference ground.
  2. Input Levels:

    • For a logic low input, ensure the voltage is below 0.8V.
    • For a logic high input, ensure the voltage is above 2.0V but does not exceed VCC.
  3. Output Levels:

    • When driving a load with a current of 8mA, the output low voltage should be between 0.1V and 0.3V.
    • When sourcing a current of -4mA, the output high voltage should be between 2.4V and VCC-0.5V.
  4. Propagation Delay:

    • The typical propagation delay time is 7ns at VCC=5V and TA=25°C. Ensure your timing requirements are met by considering this delay.
  5. Power Dissipation:

    • The maximum power dissipation per package is 100mW. Design your circuit to stay within this limit to avoid overheating.
  6. Temperature Ranges:

    • The operating temperature range is from -40°C to 85°C.
    • The storage temperature range is from -65°C to 150°C.
  7. Handling:

    • Handle the device with care to avoid static damage. Use appropriate ESD protection measures.
  8. Mounting:

    • Follow the recommended PCB layout and soldering guidelines provided by the manufacturer to ensure reliable performance.
  9. Testing:

    • After assembly, test the device under the specified conditions to verify its functionality and performance.
  10. Documentation:

    • Refer to the datasheet for detailed pin configurations, timing diagrams, and additional specifications.
