Procurement Notes

Verify the specific suffix '35' against official manufacturer documentation to confirm exact packaging or qualification variations. Ensure compatibility with existing board layouts regarding the SOIC-16 footprint. Confirm that the reel-based packaging aligns with automated assembly requirements. Cross-reference the part number with current datasheet revisions to validate active status and any recent design changes.

Selection Notes

Select this component when a unidirectional four-channel isolator is required for automotive or industrial applications. The 90 Mb/s data rate suits high-speed serial communication needs. The 2500 Vrms isolation rating provides adequate safety margins for many low-voltage systems. Consider the 3Tx/1Rx topology if asymmetric signal routing is necessary for the specific circuit design.

Part Context

This part belongs to the ADUM1401 family of iCoupler digital isolators. These devices integrate analog and digital circuits on a single monolithic CMOS substrate. The family offers various channel configurations and data rates. The ADUM1401 specifically targets applications requiring multiple isolated channels with moderate to high speed capabilities.

Replacement Considerations

Consult official substitution guides for parameter-equivalent alternatives. Verify pinout compatibility and isolation ratings before replacing. Check for updated packaging options or revised qualification statuses in newer revisions.
