PIN-TO-PIN ALTERNATIVE
NSi8221N0-DSPR is a Chinese-manufactured pin-to-pin drop-in replacement for ADuM1201 / ISO7721 (Analog Devices / Texas Instruments).
The correct bidirectional cross-reference for ADuM1201 designs, in the same SOP-8 footprint.
NSi8221N0-DSPR — Alternative to ADuM1201 / ISO7721
NSi8221N0-DSPR from Novosense {BRAND} is supplied by JTDZ Tech (Shenzhen Jingteng Electronics) as a cost-effective, short-lead-time alternative to the imported ADuM1201 / ISO7721 (Analog Devices / Texas Instruments). Chinese-sourced semiconductors have moved well beyond "cheap substitute" status: the parts below are production-validated in industrial, automotive and consumer designs, and they remove both the allocation risk and the long lead times that come with imported.

What to check before substituting NSi8221N0-DSPR for ADuM1201
- This is the channel-direction match for ADuM1201: one channel each way.
- A common substitution error is using a 2-forward part such as NSi8220 where the design needs bidirectional channels. Confirm direction from the schematic before ordering.
- Same SOP-8 footprint and wide supply range as the rest of the family.
Typical Applications
- Isolated bidirectional data links
- Isolated UART and CAN interfaces
- Motor drive feedback isolation
- Industrial I/O modules
