Procurement Notes

Verify the specific suffix (E(O) against manufacturer documentation to confirm packaging details and tape-and-reel specifications. Ensure compatibility with the target PCB footprint, specifically the 16-SOIC wide package dimensions. Confirm that the required isolation voltage rating meets system safety standards. Check RoHS compliance status if restricted substances are mandated by the end application regulations.

Selection Notes

Select this component when high-speed bidirectional or unidirectional isolation is required without shutdown functionality. Compare propagation delay and CMTI values against other isolators if signal timing precision is critical. Consider the 16-pin wide SOIC package constraints during layout design. Evaluate power consumption requirements, as the 3 mA operating current impacts overall system efficiency in battery-powered applications.
