Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage is within the specified range (4.75V to 5.25V).
   • Connect Vcc to the positive power supply and GND to ground.

2. Input Signals:

   • Apply input signals that meet the VIL and VIH specifications.
   • Ensure input currents do not exceed the maximum ratings.

3. Output Signals:

   • The output high voltage (VOH) should be at least 2.4V when the output is high.
   • The output low voltage (VOL) should be no more than 0.5V when the output is low.
   • Do not exceed the maximum output current ratings (IOH and IOL).

4. Propagation Delay:

   • Consider the propagation delay time (tpd) in your circuit design to ensure proper timing.

5. Temperature:

   • Operate the device within the specified temperature range to avoid damage.
   • Store the device in a temperature-controlled environment to prevent degradation.

6. Handling:

   • Handle the device with care to avoid static damage.
   • Follow standard ESD (Electrostatic Discharge) precautions.

7. Mounting:

   • Ensure proper mounting and soldering techniques to avoid mechanical stress and poor electrical connections.

8. Testing:

   • Test the device under controlled conditions to verify its performance before integrating it into your final design.
