Instructions for Use

1. Power Supply Connections:

   • Connect VDD1 and VSS1 to the power supply and ground on the primary side.
   • Connect VDD2 and VSS2 to the power supply and ground on the secondary side.
   • Ensure that both sides have a stable power supply within the specified range (3.0 V to 5.5 V).

2. Signal Connections:

   • Connect the input signals to the IN1 and IN2 pins.
   • Connect the output signals from the OUT1 and OUT2 pins to the respective destinations.

3. Grounding:

   • Ensure proper grounding on both sides to maintain signal integrity and reduce noise.

4. Decoupling Capacitors:

   • Place decoupling capacitors (0.1 μF) close to the VDD1/VSS1 and VDD2/VSS2 pairs to filter out high-frequency noise.

5. Layout Considerations:

   • Keep the traces between the isolator and other components as short as possible to minimize signal degradation.
   • Use a ground plane to shield the signal traces and reduce electromagnetic interference (EMI).

6. Operating Environment:

   • Operate the device within the specified temperature range (-40°C to +125°C) to ensure reliable performance.
   • Avoid exposing the device to excessive humidity or corrosive environments.

7. Handling:

   • Handle the device with care to avoid mechanical damage.
   • Follow ESD (Electrostatic Discharge) precautions to prevent damage to the device.

8. Testing:

   • Before integrating the device into a system, test it individually to ensure it meets the required specifications.
   • Use appropriate test equipment and methods to verify the performance parameters such as propagation delay, data rate, and CMTI.
