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 Levels: Inputs should be kept within the valid logic levels: low (0 to 0.8V) and high (2V to 5.25V).
3. Output Handling: Outputs are designed to drive TTL loads; ensure not to exceed the maximum current ratings.
4. Propagation Delay: Account for a propagation delay of up to 18ns in timing-sensitive applications.
5. Power Dissipation: Be mindful of the power dissipation limit of 375mW per package to avoid overheating.
6. Environmental Conditions: Optimal performance is achieved at an ambient temperature of 25°C. Adjustments may be necessary for different temperatures.
7. Handling Precautions: Follow standard ESD (Electrostatic Discharge) precautions when handling the device to prevent damage.
