The following schematic shows a circuit of differential analog switch uses FM1208 monolitic dual.

Although not common, this circuit is an ideal choice for an accurate multiplexer. It is because RDS (on) for the monolithic dual tracks at better than ± 1% over wide temperature ranges (-25 to +125 degree celcius). [Source : National Semiconductor Application Notes]
