Instructions for Use:

  1. Power Supply:

    • Ensure the supply voltage is within the specified range (2.0V to 5.5V).
    • Use a stable power supply to avoid fluctuations that can affect performance.
  2. Input Signals:

    • Apply input voltages within the specified low (0V to 1.5V) and high (3.5V to 5.5V) levels.
    • Ensure input signals are clean and free from noise to prevent incorrect operation.
  3. Output Loads:

    • Do not exceed the maximum output current ratings (sink: 24mA, source: 6mA).
    • Use appropriate load resistors to ensure the output voltage remains within safe limits.
  4. Propagation Delay:

    • Account for the propagation delay time when designing circuits to ensure proper timing.
    • Use a load capacitance of 15pF or less to minimize delay.
  5. Temperature Considerations:

    • Operate the device within the specified operating temperature range (-40°C to 85°C).
    • Store the device within the storage temperature range (-65°C to 150°C) to prevent damage.
  6. Handling:

    • Handle the device with care to avoid static discharge, which can damage the internal components.
    • Follow standard ESD (Electrostatic Discharge) precautions during handling and installation.
  7. Mounting:

    • Ensure proper mounting to a suitable PCB with adequate thermal management if necessary.
    • Follow the recommended PCB layout guidelines to ensure optimal performance and reliability.
