Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage (V_CC) is within the range of 2.0V to 5.5V.
   • Connect the ground (GND) pin to a stable 0V reference.

2. Input Signals:

   • Inputs should be within the specified input voltage range (0V to V_CC).
   • Avoid floating inputs; use pull-up or pull-down resistors as necessary.

3. Output Signals:

   • Outputs can drive loads up to 16 mA (sink) and 4 mA (source).
   • Ensure the load does not exceed the output current ratings to avoid damage.

4. Propagation Delay:

   • The propagation delay time (t_pd) is critical for timing considerations in your circuit. It is typically around 3.5 ns at 3.3V supply voltage.

5. Temperature Considerations:

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

6. Power Dissipation:

   • Monitor the power dissipation (P_D) to ensure it does not exceed 100 mW at 3.3V supply voltage.
   • Use heat sinks or other cooling methods if necessary to manage heat.

7. Handling:

   • Handle the device with care to avoid static discharge, which can damage the internal circuits.
   • Follow ESD (Electrostatic Discharge) precautions during handling and installation.

8. Testing:

   • Before finalizing the design, test the device under various conditions to ensure it meets the required performance specifications.

9. Layout Considerations:

   • Use short, direct traces for high-speed signals to minimize signal degradation.
   • Place decoupling capacitors close to the power pins to filter out noise and ensure stable operation.

10. Compliance:

    • Ensure that the device complies with all relevant safety and regulatory standards for your application.
