Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage (V_CC) is within the range of 2.0V to 6.0V.
   • Connect V_CC to the positive power supply and GND to the ground.

2. Input Signals:

   • Input signals should be within the specified input voltage levels:
     • High level (V_IH): 3.15V to V_CC
     • Low level (V_IL): 0V to 0.85V

3. Output Signals:

   • The output high level (V_OH) will be at least 2.4V when the output current (I_OL) is 0.4 mA.
   • The output low level (V_OL) will be no more than 0.1V when the output current (I_OH) is -4.0 mA.

4. Propagation Delay:

   • The typical propagation delay time (t_pd) is 8 ns. This is the time it takes for the output to change state after the input changes.

5. Temperature Considerations:

   • The device is designed to operate within a temperature range of -40掳C to 85掳C.
   • Store the device in a temperature range of -65掳C to 150掳C.

6. Handling:

   • Handle the device with care to avoid static damage.
   • Follow proper ESD (Electrostatic Discharge) precautions when handling and installing the device.

7. Mounting:

   • Solder the device onto the PCB using standard surface mount technology (SMT) techniques.
   • Ensure that the soldering temperature does not exceed the maximum storage temperature.

8. Testing:

   • Test the device under the specified operating conditions to ensure it meets the performance parameters.

9. Storage:

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