Instructions for Use:

1. Supply Voltage (V_CC):

   • Ensure the supply voltage is within the range of 2.0V to 5.5V.
   • Do not exceed the maximum supply voltage to avoid damaging the device.

2. Input Levels:

   • For a logic low input, ensure the voltage is below 1.5V.
   • For a logic high input, ensure the voltage is above 3.5V.

3. Output Levels:

   • When the output is low, the voltage will be less than 0.4V at a current of 4 mA.
   • When the output is high, the voltage will be greater than 4.5V at a current of -0.4 mA.

4. Propagation Delay (t_pd):

   • The typical propagation delay time is 8 ns at 5V supply voltage and 25掳C ambient temperature.
   • Ensure that the propagation delay is considered in timing-sensitive applications.

5. Power Dissipation:

   • The maximum power dissipation per package is 200 mW. Ensure adequate heat dissipation if operating near this limit.

6. Temperature Ranges:

   • The operating temperature range is from -40掳C to 85掳C.
   • The storage temperature range is from -65掳C to 150掳C.

7. Handling:

   • Handle the device with care to avoid static damage.
   • Use appropriate ESD protection when handling the device.

8. Mounting:

   • Ensure proper mounting and soldering techniques to avoid mechanical stress on the device.
   • Follow recommended PCB layout guidelines for optimal performance.

9. Testing:

   • Before integrating the device into a circuit, perform initial testing to verify functionality and performance.

10. Compliance:

    • Ensure that the device meets all relevant safety and compliance standards for your application.
