Procurement Notes

Verify the specific suffix 'W' indicates the wide operating temperature and automotive qualification variant compared to standard commercial grades. Confirm package type matches SOIC-8 requirements. Check current availability status as distribution may vary by region. Ensure ESD handling protocols are followed during storage and assembly. Validate that the reel packaging aligns with automated placement equipment specifications.

Selection Notes

Select this component when bidirectional isolation is required at high speeds. Consider the 3000 Vrms insulation rating for safety-critical applications. Evaluate power budget constraints against the 20 mA typical current draw. Compare propagation delay characteristics with system timing requirements. Verify compatibility with existing logic levels and supply voltages within the specified range.
