Products in this family are used for interconnecting or routing analog signals between multiple available signal paths. Functioning similar to a traditional electromechanical switch, their solid-state character facilitates electronic control, longer service life, and reduced switching noise compared to electromechanical switching, in trade for added constraints on the amplitude and bias of the signals being switched.
