I can Mux perfectly passing a high or low (Vcc and GND) through the four select pins S(0-3) to the I(0-15).
Now I need to pass a high value (VCC) from I(0-15) to select pins (S0-3)
"They are bidirectional switches thus allowing any analog input to be used as an output and vice-versa."
I can not pass those 16 values to four.
Maybe I am misunderstanding the demux part of this chip?
Perhaps I need a different kind of component for the second part of my operation?
Any input or suggestions would help thanks.
