Procurement Notes

Verify the specific suffix designation carefully during procurement. The 'I' suffix indicates an industrial temperature rating, while 'S' denotes a commercial variant. Confirm that the required isolation voltage and channel count match the application requirements. Ensure compatibility with the 32-pin BGA footprint and reflow soldering profiles specified in the datasheet. Check current availability status as supply may be limited.

Selection Notes

Select this component when a compact solution is needed for multiple isolated digital lines. The integrated power supplies reduce external component count compared to discrete isolators. Consider the 2500 Vrms insulation rating for basic isolation requirements. Evaluate the 30 kV/µs CMTI for environments with high noise or fast switching transients. Ensure the operating temperature range aligns with the industrial specification if used in harsh conditions.
