Instructions for Use:

  1. Power Supply:

    • Ensure the supply voltage (VCC) is within the range of 4.75V to 5.25V to avoid damage to the device.
    • Use a stable power supply to maintain consistent operation.
  2. Input Signals:

    • Input signals should be within the specified input high (VIH) and input low (VIL) voltage levels to ensure proper logic recognition.
    • Avoid floating inputs; use pull-up or pull-down resistors if necessary.
  3. Output Signals:

    • The output high level (VOH) and output low level (VOL) voltages should be within the specified ranges to ensure reliable operation with connected devices.
    • Ensure the load current does not exceed the maximum output current ratings.
  4. Propagation Delay:

    • The propagation delay time (tpd) is critical for timing considerations in digital circuits. Use this value to synchronize operations with other components.
  5. Thermal Management:

    • The device can dissipate up to 650 mW at room temperature. Ensure adequate heat dissipation if operating near the maximum power dissipation.
    • Operate the device within the specified temperature range to avoid thermal stress and potential failure.
  6. Storage:

    • Store the device in a controlled environment within the storage temperature range to prevent damage from extreme temperatures.
  7. Handling:

    • Handle the device with care to avoid static discharge, which can damage the internal circuitry.
    • Follow ESD (Electrostatic Discharge) precautions when handling and installing the device.
