which CMOS pins to ground?

  1. The ground and VL pins power the logic section that must
    match the voltage swing of the controlling signals. Unused
    controls can be tied either to ground of to VL.

    V+ and V= power the switches, themselves, and those rails
    must contain all analog signals passing through the
    switches. VL and Ground must be inside the V- to V+ range.

    The unused switch connections (COM, NO, NC) may be left
    floating or tied to any voltage between V- and V+.

    Set your PC clock right, idiot.

    Sorry, I don't follow. So do I connect the idiot to ground, or the clock to
    ground, or both? Or can they just be left floating?

    Hey all;

    I'm experimenting with a CMOS analog switch (MAX4662). It's got 4 switches
    in it and can be run on +/- or single supply. I'm only using 1 of the
    switches at the moment, and I'm running it singel supply. Which of the
    remaining pins need to be grounded? I was thinking just the com pins (and
    not the NC or NO), but then got wondering about V-.....
