I have a few discontinued Pololu 4-ch RC multiplexers, item #721, which were replaced with #2806.
I have two questions:
Can someone confirm that on the newer multiplexer #2806, the power pins S1-S4 are connected? This isn’t true for item #721, the power pins on S1-S4 are not connected (at least on my boards, which i tested with a multimeter). I planned to distribute power over the slave pins as this will simplify my design, I think I will buy a few of the new multiplexers but I wanted to confirm before buying.
Are the schematics for item #721 and #2806 available somewhere? I could not find them through the webpage / google, having the schematic would have saved me some trouble.
