Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage (V_CC) is within the range of 4.75 V to 5.25 V.
   • Connect the ground (GND) pin to the system ground.

2. Input Signals:

   • Apply input voltages (V_IH and V_IL) that meet the specified levels to avoid undefined behavior.
   • Ensure input currents (I_IH and I_IL) do not exceed the maximum ratings to prevent damage.

3. Output Signals:

   • The output voltages (V_OH and V_OL) should be within the specified limits under the given load conditions.
   • Do not exceed the maximum output currents (I_OH and I_OL) to avoid overheating or damage.

4. Propagation Delay:

   • The propagation delay times (t_pd(H-L) and t_pd(L-H)) are critical for timing considerations in your circuit. Ensure these values are accounted for in your design.

5. Temperature:

   • Operate the device within the temperature range of -40掳C to 85掳C to ensure reliable performance.

6. Power Dissipation:

   • The maximum power dissipation is 500 mW. Ensure adequate heat dissipation if operating near this limit.

7. Storage and Handling:

   • Store the device in a dry environment and handle with care to avoid static damage. Use proper ESD protection when handling the device.

8. Schematic Integration:

   • Refer to the datasheet for detailed pin configurations and recommended layout guidelines to ensure optimal performance.
