Procurement Notes

Verify the specific suffix 'W' or absence thereof against official datasheets, as packaging and moisture sensitivity levels may vary. Confirm AEC-Q100 qualification status for your specific application environment. Check RoHS compliance details directly from manufacturer documentation. Ensure compatibility with your system's voltage levels and signal integrity requirements before finalizing procurement decisions.

Selection Notes

Select this component when high isolation voltage and automotive qualification are required. Consider the 150 Mbps speed limit for bandwidth needs. Evaluate the 8-SOIC footprint against PCB space constraints. Compare CMTI specifications if operating in high-noise environments. Verify supply voltage range matches your system design.
