Part Number: ISO1450
Other Parts Discussed in Thread: ISOW7742, ISOW7842

Hello Sir:

We are searching isolate RS232 interface, our competitor is ADM3251EARWZ.

Do we have solution for replacing ADM3251EARWZ?

Please help to provide your recommendations.

Thanks a lot.

    Hi Statham,

    Thanks for reaching out.

    We currently do not have an integrated isolation solution for RS-232 interface instead we have a discrete solution. Please refer to the below reference design which implements isolated RS-232 solution using two devices. We now have our second-generation ISOW device, hence I recommend you to suggest ISOW7742 in place of ISOW7842.

    Let me know if you have any questions, thanks.
