If yes then how can I give it input and select lines? What, exactly, do you think the function of pins 1 and 15 datashert Wouter van Ooijen Thanks for simplifying the answer. I just better understood the concept from you than from Tom’s answer. So I will accept it. In your first paragraph you say that a demux requires: Thanks for the answer.

Before taking a look at demux, I actually took a look at mux’s datasheet, where I saw an Enable input, to enable or disable mux. So, I compared it to Demux’s Enable input. So, I was confused.
