ADUM6404 ISOLATOR FOR RS422 APPLICATION

Dear sir,

I read the ADUM6404 digital isolator datasheet perfectly....For my application i want to use this IC for isolating the RS422 signals from one ground to another ground before going to RS422 line receiver.....

So i want clear clarification about this ADUM6404 is used or not for RS422 application for isolating the RX+ and RX- from one side to another side....

    Hi Sandeep, 

    RS422 is a differential signal. The ADuM6404 has single-end I/O, and the levels are not compatible. 

    For RS-422 to RS-422 isolation (or an isolated repeater) we could use a non-isolated transceiver (ADM3067E for example) and an isolated RS-422 transceiver (ADM2463E for example)

    Regards,

    Jason
