ISO1432: ISO1432B can support RS-485 and RS-422 at the same time
Part Number: ISO1412
we are designing system with RS422 interface.
we deciided to have ISO1412B RS422 transceiver with isolation IC in our design.
i have studied the datasheet and specified that 2 separate power supplies and 2 separate ground are required.
In my PCB, i am having only one 3.3V voltage supply and one Ground.
In Reference design, i have seen other circuit is used i.e. SN6505, TPS76350
Whether both power supplies, grounds should be isolated or not.
We have THVD14xx family that is non-isolated RS-485 transceiver and have ISO14xx family which is isolated version of THVD14xx. If you do not need isolation then a device from THVD14xx family should meet your requirement. If you need isolation then you can choose from ISO14xx family.
Please do share more details related to your application and I may be able to help you decide whether you need isolation. Thanks.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

i need iso1412b schematic
In reply to JAYALAKSHMI kanukunta:
i need iso1412b orcad file
We have the files only in Altium, you should be able to import them into OrCAD. I believe you were already able to create your schematic using ISO1412, as you have mentioned in another post. Hence, I will go ahead and close this. Thanks.
