Instructions for Use:

  1. Power Supply:

    • Ensure that the supply voltage (VCC) is within the range of 4.75V to 5.25V.
    • Connect the ground (GND) pin to a stable reference ground.
  2. Input Signals:

    • Input signals should be within the specified input voltage levels:
      • Low level (VIL): 0.8V or less
      • High level (VIH): 2.0V or greater
  3. Output Signals:

    • Output signals will be within the following levels:
      • Low level (VOL): 0.4V or less
      • High level (VOH): 2.4V or greater
  4. Propagation Delay:

    • The typical propagation delay time (tpd) is 15 nanoseconds. This is the time it takes for the output to respond to a change in the input signal.
  5. Power Dissipation:

    • The maximum power dissipation (Ptot) is 350 milliwatts. Ensure that the device is not operated beyond this limit to avoid overheating.
  6. Temperature Range:

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

    • Handle the device with care to avoid static discharge, which can damage the internal components.
    • Use appropriate ESD (Electrostatic Discharge) protection when handling the device.
  8. Mounting:

    • Ensure proper mounting on the PCB to maintain good thermal management and mechanical stability.
  9. Testing:

    • Before finalizing the design, test the device under various conditions to ensure it meets the required performance specifications.
  10. Documentation:

    • Refer to the datasheet for detailed information and specific application notes.
