Instructions for Use:

  1. Power Supply:

    • Connect VCC to the positive supply voltage (2.0V to 6.0V).
    • Connect GND to the ground.
  2. Input Signals:

    • Ensure input signals are within the specified range for VIL and VIH.
    • Do not exceed the maximum input current ratings.
  3. Output Signals:

    • Ensure load currents do not exceed the maximum output current ratings.
    • Check the output voltage levels to ensure they meet the required logic levels.
  4. Propagation Delay:

    • Account for the propagation delay time when designing timing-sensitive circuits.
  5. Temperature Considerations:

    • Operate the device within the specified temperature range to avoid damage.
    • Store the device in the recommended storage temperature range.
  6. Handling:

    • Handle the device with care to avoid static discharge, which can damage the internal circuitry.
    • Follow proper soldering techniques to prevent thermal shock.
  7. Decoupling Capacitors:

    • Place decoupling capacitors close to the power pins to minimize noise and ensure stable operation.
  8. Pin Configuration:

    • Refer to the pinout diagram provided in the datasheet to correctly connect all pins.
  9. Testing:

    • Perform initial testing under controlled conditions to verify correct operation before integrating into a larger system.
