Procurement Notes

Verify component authenticity through authorized distribution channels due to the part's obsolete status. Confirm that substitute components meet identical AEC-Q100 automotive qualifications and pinout compatibility. Ensure replacement devices maintain the required 15 kV/µs CMTI and 5000 Vrms isolation specifications for safety compliance. Validate thermal performance characteristics against original datasheet limits before integration into final assemblies.

Selection Notes

Select this component for applications demanding high-speed digital isolation in automotive contexts. Consider the push-pull output structure for driving capacitive loads efficiently. Evaluate the SO-12 footprint for PCB space constraints. Verify that the 20 mA forward current rating aligns with LED drive requirements. Assess the -40°C to +125°C operating range against environmental conditions.
