ISO7721: Side1/Side2 diff.

Part Number: ISO7721


Tool/software:

Hello,

I would like to use ISO7721 as an UART interface isolator (between onboard mCU and another external device). I just went through documentation and I didn't any difference between side 1 and side 2 of ISO isolator - It looks completly optional on which side a mCU and which side an external device is connected to ISO7721, am I right?

Many thanks, Kind regards.
