iCouplers from analog claim to be bidirectional. Steve Smith escribi=F3: A transformer is naturally= bidirectional you need two optos Just a thought !

Subject: [EE] A<--> Optoisolators (comm) <--> B Hello, I have two systems A and B. I'd like to have a robust optically isolated communication line (going real time). I have choose RS-232/422/485 as possible communication protocols. = I have been searching the net for optoisolators, there are a huge amount of those, but thinking that communication is bidirectional and it could be fast, what are more suitable optoisolators for doing such a thing ? I have been looking to (new) analog iCouplers[1], those look good, but i need good MTBF and good support in the future. = Any other good idea ? Thanks !
