[sdiy] spdt analog switch?

[gavin]

Does anyone know of an analog IC switch that can do what the 4016 does
except in a sdpt configuration rather than spst?  I want to switch from
signal to ground rather than from signal to no signal, based on a logic
pulse, something like high goes to one signal, low goes to another.  I have
a old analog harmonizer schematic that shows an IC like this and labels it
as a 4053, but research on that part number turns up a
multiplexer/demultiplexer.
