Procurement Notes

Verify the specific suffix designation against official Analog Devices documentation to confirm package type and reel configuration. Confirm current product status as obsolete or active through authorized distributors. Ensure compliance with RoHS directives and check moisture sensitivity levels prior to surface mount assembly. Validate that the received component matches the exact part number including all trailing characters to avoid functional mismatches.

Selection Notes

Select this component when four-channel unidirectional isolation is required for automotive-grade applications. Consider the 2500 Vrms isolation rating and 25 kV/µs CMTI for high-noise environments. Evaluate the 34 ns propagation delay against system timing requirements. Ensure the 16-SOIC package fits the PCB layout constraints. Verify compatibility with the 2.7 V to 5.5 V supply range of the host system.
