Instructions for Use:

  1. Power Supply:

    • 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 Signals:

    • Input signals should be within the valid logic levels:
      • Low level (VIL): 0.8V or less when VCC is between 4.5V and 5.5V.
      • High level (VIH): 2.0V or more when VCC is between 4.5V and 5.5V.
  3. Output Signals:

    • Output signals will be:
      • Low level (VOL): 0.4V or less when sourcing 8mA, with VCC between 4.5V and 5.5V.
      • High level (VOH): 2.4V or more when sinking -0.4mA, with VCC between 4.5V and 5.5V.
  4. Propagation Delay:

    • The propagation delay time (tpd) is typically 6ns at VCC = 5V and TA = 25°C.
  5. Temperature Considerations:

    • The device can operate within a temperature range of -40°C to 85°C.
    • Store the device in an environment within the same temperature range.
  6. Power Dissipation:

    • Ensure that the power dissipation (PD) does not exceed 100mW to avoid overheating and potential damage.
  7. Handling:

    • Handle the device with care to avoid static discharge which can damage the internal circuits.
    • Follow standard ESD (Electrostatic Discharge) precautions when handling and installing the device.
  8. Testing:

    • Test the device under the specified conditions to ensure proper functionality.
    • Use a reliable power supply and appropriate test equipment to verify the performance parameters.
