The Intersil ISL54405IRUZ-T ISL54405 is a single supply, bidirectional, dual  single-pole/double-throw (SPDT) ultra low distortion, high  OFF-Isolation analog switch that can pass analog signals that  are positive and negative with respect to ground. It is primarily  targeted at consumer and professional audio switching  applications such as computer sound cards and home theater  products. The inputs can accommodate ground referenced  signals up to 2VRMS while operating from a single 3.3V or 5V DC  supply. The digital logic inputs are 1.8V logic-compatible when  using a single 3.3V or 5V supply. It can be used in both AC or DC  coupled ground referenced applications.
