Hi, for my experiment powered by 2 AAAs (around 2.6V) I need multiplexer. Only mux I have is CD4051 with recomended operating range 3-20 V. I tried to use it anyway until I get 74HC4051 with voltage range 2-6V. It seems to work flawlessly. I noticed before chips work at lower voltage than rated see…

Running chip at low voltage
