Digital Isolators Procurement Notes

Verify current availability status as distribution may be limited or restricted. Confirm the specific suffix matches the required bidirectional configuration and reel packaging format. Ensure compatibility with the target application's voltage levels and thermal requirements before finalizing procurement orders.

Digital Isolators Selection Notes

Select this component when bidirectional communication is required across the isolation barrier. The integrated transformer driver simplifies design compared to discrete solutions. Verify that the 25 Mb/s data rate meets system timing constraints. Consider the 20-SSOP footprint for PCB layout planning.

Digital Isolators Part Context

This part belongs to the ADUM347x series of high-speed digital isolators. It shares the same core architecture and package style as other variants in the family, differing primarily in channel directionality and specific electrical characteristics. The WCRSZ designation indicates the bidirectional variant in reel packaging.

Digital Isolators Replacement Considerations

Direct substitutes include other ADUM347x variants such as ADUM3471 or ADUM3473, provided the unidirectional configuration aligns with the circuit design. Cross-model substitution requires verification of pinout compatibility and functional directionality differences.
