ISO1541: Can ISO1541 used as the normal UART isolation

Part Number: ISO1541
Other Parts Discussed in Thread: ISO7721

Hi team,

Because the ISO1541 is in my customer's device library. So they want to use the chip as the UART isolation. Can the chip be used like this? If cannot , i will promote the ISO7321 to the customer. Thank you.

  • Hi Frank,

    ISO1541 is designed and optimized for I2C communication, Hence it wouldn't be suitable to use with UART. Also ISO1541 would limit the data rate in UART application and wouldn't fetch much advantage over Digital Isolators.

    I would recommend customer to use ISO7321 if basic isolation is required and use ISO7721 if reinforced isolation required.

    Please let me know if you have any further queries.
