Instructions for Use:

  1. Supply Voltage (VCC):

    • Ensure the supply voltage is within the range of 4.75V to 5.25V to avoid damage to the device.
  2. Input Levels:

    • Input low voltage (VIL) should be less than or equal to 0.8V.
    • Input high voltage (VIH) should be greater than or equal to 2.0V.
  3. Output Levels:

    • Output low voltage (VOL) will be between 0.25V and 0.5V.
    • Output high voltage (VOH) will be between 2.7V and 3.5V.
  4. Propagation Delay Time (tpd):

    • The typical propagation delay time is 22ns, with a minimum of 15ns and a maximum of 35ns.
  5. Power Dissipation (PD):

    • The maximum power dissipation is 100mW. Ensure proper heat dissipation if operating near this limit.
  6. Operating Temperature (TA):

    • The device is designed to operate within a temperature range of -40°C to 85°C.
  7. Storage Temperature (TSTG):

    • Store the device in a temperature range of -65°C to 150°C to ensure long-term reliability.
  8. Handling:

    • Handle the device with care to avoid static discharge, which can damage the internal circuitry. Use proper ESD protection measures.
  9. Mounting:

    • Ensure that the device is properly mounted on the PCB to avoid mechanical stress and ensure good electrical connections.
  10. Testing:

    • Before integrating the device into a larger system, test it individually to ensure it meets the specified parameters.
