Instructions for Use:

  1. Power Supply:

    • Ensure the supply voltage (VCC) is within the range of 2.0 V to 6.0 V.
    • Connect the ground (GND) pin to a stable reference potential.
  2. Input Signals:

    • Apply input signals (VIN) that meet the specified high (VIH) and low (VIL) voltage levels.
    • Avoid exceeding the maximum input voltage (VCC) or going below ground (0 V).
  3. Output Signals:

    • The output voltage (VOH and VOL) will be within the specified ranges when driving the specified current loads.
    • Ensure the load resistance is appropriate to maintain the output voltage levels within the specified limits.
  4. Propagation Delay:

    • The propagation delay time (tpd) is critical for timing considerations in digital circuits. Ensure that the delay meets the requirements of your application.
  5. Thermal Management:

    • The power dissipation (PD) should not exceed 100 mW to prevent overheating. Use proper heat sinking if necessary.
  6. Temperature Range:

    • The device is rated for operation over a temperature range of -40°C to 85°C. Ensure the operating environment does not exceed these limits.
  7. Handling:

    • Handle the device with care to avoid damage from electrostatic discharge (ESD). Use appropriate ESD protection measures during handling and installation.
  8. Testing:

    • Before integrating the device into a circuit, test it under controlled conditions to ensure it meets the specified parameters.
  9. Schematic and Layout:

    • Follow recommended schematic and layout guidelines to ensure optimal performance and reliability. Keep signal paths short and use decoupling capacitors near the power pins to reduce noise.
  10. Storage:

    • Store the device in a dry, cool place away from direct sunlight and sources of heat or moisture.
