Instructions for Use:

  1. Power Supply:

    • Ensure the supply voltage (VCC) is within the range of 2.0V to 6.0V.
    • Connect VCC to the positive power supply and GND to the ground.
  2. Input Signals:

    • For valid low input (VIL), ensure the voltage is between -0.5V and 0.8V.
    • For valid high input (VIH), ensure the voltage is between 2.0V and 5.5V.
  3. Output Signals:

    • When the output is low (VOL), the voltage should be between 0.0V and 0.1V.
    • When the output is high (VOH), the voltage should be between 2.7V and VCC - 0.2V.
  4. Propagation Delay:

    • The propagation delay time (tPLH and tPHL) is typically 8ns under standard conditions (VCC = 5V, VOH = 3.5V, VOL = 1.5V, CL = 50pF).
  5. Power Dissipation:

    • The maximum power dissipation per package is 500mW. Ensure proper heat dissipation if operating near this limit.
  6. Temperature Ranges:

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

    • Handle the device with care to avoid static damage.
    • Follow proper ESD (Electrostatic Discharge) precautions during handling and installation.
  8. Mounting:

    • Ensure the device is securely mounted on the PCB with appropriate soldering techniques.
    • Verify that all connections are correct and secure before powering the circuit.
  9. Testing:

    • Test the device under typical operating conditions to ensure it meets the specified performance parameters.
    • Use a multimeter or oscilloscope to verify input and output voltages and timing characteristics.
