I am designing a circuit which will have some external I2C sensors connected to it and thus I want to protect it from noise - via an optocoupler. I have to say that I am a complete novice to this all and after much searching, I came up with following source: Opto-electrical isolation of the I2C-Bus
The thing is, I would ideally like to see an IC, which would have two sides and I would plug in power + signal lines of the both sides into either side and it would do it all, without any extra complexity. I have looked at RS components but to be honest, it just makes my head spin and I cannot really see which one to choose. Which IC can I use here?
