INTEGRATED CIRCUI CMOS ANALOG SINGLE 8-CHANNEL MULTIPLEXER/DEMULTIPLEXER SOIC-16

hey guys welcome back to the 4000 series series where we're looking at some of the 4000 series CMOS chips this one we're looking at is the 40 51 it's an analog multiplexer and demultiplexer essentially it's an analog switch it will give you one common output input and also eight input and output so you can use so it's like switching these eight input or outputs over to this common one essentially that's what happens so you could use that as an input put in an analog signal a voltage and then that voltage can be output onto any one of these other outputs here or you can use that as the output and have eight separate inputs that you can switch now I've rigged up a little circuit just to demonstrate the common IO so I'm using that as an output and these separate ones as an input we're using some voltage dividers so I'm just using some resistive voltage dividers here I've got them all detai
