Yes, I have already tested it. Here the schematic.
The 4093 sinks only a few microamperes.

Any thoughts on what would be a reasonable power drain with any given FET? I
have some small-signal ones, and some medium-power ones (TO220 pkg) that
I've salvaged...

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?
