Hi,
I have a DG406 Multiplexer but I'm having difficulty making it work, I've searched around for a "typical circuit" or a pin description but have found nothing useful. I understand pins A0-A3 need an input of more than 2.5V I think it is to select, enable has to be high with >2.5V also. I have 5V connected to V+ and GND connected to GND. What does V- have to be connected to as I have it connected to GND at the moment and dont have a -5V supply. Finally what does D do? It's really confusing as I don't know whether to connect it to GND or 5V, tried both but no results. with nothing connected to A0-A3, S1 should light up but it doesn't, that's with it setup to be connected with 5V, GND, EN and V- to GND.
Any help would be appreciated,
George S.
