Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage (VCC) is within the range of 1.65V to 3.6V.
   • Connect VCC to the positive supply and GND to the ground.

2. Input Signals:

   • For a valid low input, the voltage should be less than or equal to 0.8V.
   • For a valid high input, the voltage should be greater than or equal to 2.0V.

3. Output Signals:

   • The output will be considered high when the voltage is greater than or equal to 2.4V.
   • The output will be considered low when the voltage is less than or equal to 0.4V.

4. Propagation Delay:

   • The typical propagation delay time (tpd) is 2.9 nanoseconds. This is the time it takes for the output to respond to a change in the input signal.

5. Temperature Considerations:

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

6. Power Dissipation:

   • The maximum power dissipation is 340 milliwatts. Ensure proper heat dissipation if operating near this limit.

7. Handling:

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

8. Mounting:

   • Follow standard surface mount technology (SMT) procedures for mounting the device on a PCB.

9. Testing:

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