Procurement Notes

Verify the specific suffix '000E' to ensure compliance with RoHS standards and lead-free manufacturing requirements. Confirm that the 5-SOIC package dimensions match your PCB footprint constraints. Ensure the selected variant meets the required isolation voltage ratings for your safety certification needs. Cross-reference the datasheet for any recent updates regarding recommended operating conditions or thermal management guidelines.

Selection Notes

Select this component when high-speed digital isolation is critical for system performance. The push-pull output eliminates the need for external pull-up resistors, simplifying circuit design. Consider the 15 kV/µs CMTI rating for applications with significant switching noise. Verify that the 3 V to 5.5 V supply range aligns with your system's logic levels. Evaluate the thermal performance within the -40°C to 125°C range for your specific enclosure conditions.
