Thread Summary

                The user inquired about using the ADuM6404 for isolating RS422 signals. The final answer clarified that the ADuM6404 is not suitable due to its single-end I/O, and recommended using a non-isolated transceiver (ADM3067E) with an isolated RS-422 transceiver (ADM2463E) for proper isolation.

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
