Instructions for Use:

  1. Power Supply:

    • Ensure the supply voltage (Vcc) is within the specified range of 4.5V to 5.5V.
    • Connect Vcc to the power supply and GND to ground.
  2. Input Signals:

    • Apply input signals within the logic levels defined by the device.
    • Ensure input currents do not exceed the maximum ratings.
  3. Output Signals:

    • The device can source up to 4.0mA and sink up to 16.0mA.
    • Ensure load resistances are appropriate to avoid exceeding these limits.
  4. Propagation Delay:

    • Account for the propagation delay time (tpd) in your timing calculations, which can range from 10ns to 30ns.
  5. Thermal Management:

    • Operate the device within the specified temperature range (-40°C to 85°C).
    • Store the device in environments where temperatures do not exceed the storage temperature range (-65°C to 150°C).
  6. Handling:

    • Handle the device with care to avoid static discharge.
    • Follow proper soldering techniques to ensure reliable connections.
  7. Testing:

    • Test the device under typical operating conditions to verify functionality.
    • Use a multimeter or oscilloscope to measure voltages and currents as needed.
  8. Storage:

    • Store the device in a dry, cool place to prevent damage.
    • Keep the device in its original packaging until ready for use.
