Procurement Notes

Verify the specific suffix 'RL' indicates reel packaging when sourcing. Confirm availability status as some distributors may list limited stock or special order requirements. Ensure the 16-SOIC footprint matches the target PCB design. Check RoHS compliance documentation for regulatory adherence. Validate the 3750 Vrms isolation rating against system safety requirements.

Selection Notes

Select this component for applications requiring four isolated bidirectional or unidirectional channels with high speed. Consider the 150 Mb/s data rate limit for interface compatibility. Evaluate the 1.8 V to 5 V supply range against system power rails. Assess the thermal performance within the -40°C to +125°C operational window. Compare the 16-SOIC package dimensions against available board space constraints.
