Instructions for Use:

1. Power Supply: Ensure the supply voltage (VCC) is within the specified range of 4.75V to 5.25V.
2. Output Levels: Verify that the output voltages are within acceptable limits when driving loads, ensuring VOH is at least 2.4V and VOL does not exceed 0.4V.
3. Input Handling: Be aware of input leakage currents, which should not exceed 卤1渭A to prevent unintended operation.
4. Timing Considerations: Account for propagation delays in timing-sensitive applications, with a typical delay of 3.6ns.
5. Power Management: Monitor power consumption, keeping in mind the quiescent supply current of approximately 10mA.

For detailed application-specific guidelines, refer to the manufacturer's datasheet or technical documentation.
