Procurement Notes

Verify the specific suffix WCRZ-RL7 against official Analog Devices documentation to confirm package type and reel quantity. Ensure compatibility with existing PCB footprints for SOIC-8 packages. Check regional availability as distribution may be limited or restricted in certain areas. Confirm RoHS compliance status through manufacturer datasheets prior to integration.

Selection Notes

Select this component when bidirectional isolation is required for automotive or industrial signals. The 25 Mb/s rate suits standard SPI and UART protocols. Consider the 45 ns delay for timing-critical designs. Verify thermal requirements for the SOIC-8 package in enclosed enclosures. Compare against non-automotive variants if AEC-Q100 certification is not mandatory for the target application.
