Instructions:

1. Supply Voltage: Ensure the supply voltage (VCC) is within the specified range of 2.0V to 6.0V.
2. Input Levels: Inputs should be set to either a valid logic low (VIL) or logic high (VIH) level as defined in the table.
3. Output Levels: Outputs will provide either a valid logic low (VOL) or logic high (VOH) level depending on the internal state.
4. Current Handling: Be aware of the typical input leakage current and ensure external circuitry can handle the specified output drive current.
5. Timing Considerations: Account for the propagation delay time when designing circuits that depend on timing.
6. Power Management: Do not exceed the maximum power dissipation rating to avoid overheating and potential damage.

Note: Always refer to the manufacturer's datasheet for the most accurate and detailed specifications and guidelines.
