Hi Marco,
I put a little schematic here:

May be it is what you are looking for.
Looking at that, I was thinking of some variations on the circuit...

Suppose instead of a bipolar transistor driving a relay, you used just a FET.
Maybe some kind of a power FET. The circuit could then be used for
controlling the power to a bunch of other stuff, toggling on and off states,
and "off" would only draw as much current as the 4093 needed while in a
static condition, or not very much at all.

What do you guys think of that idea?
