Instructions for Use:

  1. Power Supply:

    • Ensure the supply voltage (VCC) is within the range of 4.75V to 5.25V.
    • Connect VCC to the positive supply and GND to the ground.
  2. Input Signals:

    • For a high-level input, ensure the voltage (VIH) is at least 2.0V and can go up to VCC.
    • For a low-level input, ensure the voltage (VIL) is between 0V and 0.8V.
  3. Output Signals:

    • When the output is high, the voltage (VOH) should be at least 2.4V and can reach VCC - 0.1V.
    • When the output is low, the voltage (VOL) should not exceed 0.5V.
  4. Propagation Delay:

    • The typical propagation delay time (tpd) is 23 ns at room temperature (25°C).
  5. Power Dissipation:

    • The maximum power dissipation per package is 100 mW. Ensure adequate heat dissipation if operating near this limit.
  6. Temperature Ranges:

    • 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 damage from static electricity. Use appropriate ESD protection measures.
  8. Mounting:

    • Ensure proper mounting and soldering techniques to avoid thermal and mechanical stress on the device.
