Hi all,
in a RS485 System with 2 nodes, is it possible that one transceiver is supplied with 5V and one transceiver is supplied with 3,3V (withour levelshifter)? I tried this with the THVD1500 and it is working, but i'm not sure if it will lead to any problems.
In my opinion this should work, because on long cable transmission, there is also a chance for differences in power supply and ground potential.
Best regards
