There's a number of devices prefixed DG, eg DG211 quad analog switch, similar to a 4066 but with much more versatile supply rails. 4000 series tends to be lowest cost though and often wins for that reason alone. The maxim website is worth a look, maxim-ic.com. Some of their ICs have specified levels of ESD resistance.
