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.

Hi Jayalakshmi,

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.

Hi Jayalakshmi,

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.
