Hey guys,
I'm currently designing a multiplexing circuit based on the MCP23017-E/SP for digital I/Os and the MC14051BCP or CD4051BE for the analog I/Os. My concern is that I want to connect a current sensor (ACS712) connected to the analog multiplexers. In case they fail and somehow the 220V get to the pins of the multiplexers everything will go south really quick. What would be the best approach to keep everything safe?
Thanks in advance!
