Using Analog Switch ICs?
theatrical scene:
Super basic question, I'm using a MC14016 quad analog switch (https://www.onsemi.com/pub/Collateral/MC14016B-D.PDF) and from reading the datasheet it isn't immediately obvious wondering whether the 'inputs' and 'outputs' are indeed bilateral/bidirectional in that I could feed in a voltage from the output side and read it from the input side or is there an internal diode-like structure which means current can only flow one way?
amyk:
Yes. They are internally constructed as a CMOS transmission gate so they are bidirectional.

Thanks, are the 'in' and 'out' markings used on the datasheet generally irrelevant/to be used as a guide then in this case?

Irrelevant.

Yes, look at the internal schematic for an analogue switch.
