    Hi Jimmy Wang, 

    Thank you very much for reaching out. 

    Are you using ADuM4221 with a SOIC16-lead wide body package? If you were using this package previously and you are traying to use our SOIC 14-lead wide body package, you will be gaining in channel to channel creepage and clearance by using our device.

    Another important specification to keep in mind when replacing the devices will be to ensure that the supplies for VCCI and VDDx are as defined in the recommended table to the UCC21320-Q1 device.

    In addition to this feel free to share with us any schematics and layout for a detailed schematic review for your system.
