Using this level-shifting 3-to-8 demultiplexer scheme allows flexible control of the analog switches without
directly coupling them to the digital power supplies. With eight possible decoded outputs from three GPIO
pins, multiple combinations of on / off analog switch arrangements are possible.
Independent dual analog switches for each differential channel help to eliminate crosstalk between them.
