Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage (VCC) is within the specified range of 2V to 6V.

2. Input Signals:

   • Apply input signals that are compatible with the supply voltage. The input leakage current should be considered when designing circuits to avoid unnecessary power consumption.

3. Output Handling:

   • Be cautious of the output short-circuit current limit of 卤25mA. Avoid conditions that could cause excessive current draw from the outputs.
   • For optimal performance, keep the output high and low voltages within the specified limits to ensure reliable logic levels.

4. Propagation Delay:

   • Account for the propagation delay time in timing-sensitive applications. The typical delay is around 8ns under standard operating conditions.

5. Thermal Management:

   • Monitor the power dissipation per package. Ensure adequate heat dissipation if operating near the maximum power dissipation limit.

6. Handling Static Electricity:

   • Handle the device with care to prevent damage from static electricity. Use appropriate ESD protection measures during handling and assembly.

7. Storage and Operation Temperature:

   • Store and operate the device within recommended temperature ranges to ensure long-term reliability and performance.

Note: Always refer to the manufacturer's datasheet for the most accurate and detailed information specific to your application requirements.
