Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage (V_CC) is within the range of 1.8V to 6.0V.
   • Connect V_CC to the positive power supply and GND to the ground.

2. Input Signals:

   • Apply input signals (V_IH or V_IL) that meet the specified voltage levels.
   • Ensure the input current (I_IH or I_IL) does not exceed the maximum ratings.

3. Output Signals:

   • The output signals (V_OH or V_OL) will be driven according to the input signals.
   • Ensure the output current (I_OH or I_OL) does not exceed the maximum ratings.

4. Propagation Delay:

   • The propagation delay time (t_pd) is the time it takes for the output to change state after the input changes.
   • This value is typically 3.5ns at V_CC = 5V with a load current of 卤10mA.

5. Power Dissipation:

   • The total power dissipation (P_D) should not exceed 100mW per package to avoid overheating.

6. Handling:

   • Handle the device with care to avoid electrostatic discharge (ESD) damage.
   • Follow proper soldering techniques to ensure reliable connections.

7. Storage:

   • Store the device in a dry, cool place to prevent moisture damage.

8. Testing:

   • Test the device under typical operating conditions to ensure proper functionality.
