Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage (V_CC) is within the specified range (4.75 V to 5.25 V).
   • Connect the ground (GND) pin to a stable 0 V reference.

2. Input Signals:

   • Apply input signals (V_IH or V_IL) that meet the specified voltage levels.
   • Ensure input currents do not exceed the maximum ratings.

3. Output Signals:

   • Verify that the output voltages (V_OH or V_OL) are within the specified limits under the given load conditions.
   • Do not exceed the maximum output current ratings.

4. Propagation Delay:

   • Account for the propagation delay time (t_pd) in your circuit design to ensure proper timing.

5. Thermal Considerations:

   • Monitor the power dissipation (P_D) to avoid overheating. Use appropriate heat sinks if necessary.

6. Storage and Handling:

   • Store the device in a dry, static-free environment.
   • Handle with care to avoid damage to the pins and package.

7. Testing:

   • Test the device under typical operating conditions to ensure it meets the specified performance parameters.
