Instructions for Use:

1. Power Supply: Ensure the supply voltage (V_CC) is within the specified range of 4.75V to 5.25V.
2. Input Signals: Apply input signals that meet the minimum and maximum voltage thresholds for logic low (V_IL) and high (V_IH).
3. Output Loads: Connect loads ensuring the output voltages remain within the limits for logic low (V_OL) and high (V_OH) under specified current conditions.
4. Timing Considerations: Account for the propagation delay time (t_p) in your circuit design to ensure proper timing.
5. Thermal Management: Keep power dissipation within the limit of 500mW per package to avoid overheating. Implement appropriate heat sinking if necessary.
6. Handling Precautions: Handle the device with care to avoid damage from electrostatic discharge (ESD) and ensure all connections are secure and correct.
