Description The FSA223 is a Double-Pole, Double Throw (DPDT) multiplexer that combines a low-distortion audio and a USB2.0 High-Speed (HS) switch path. This configuration enables audio and USB data to share a common connector port. The architecture is designed to allow both audio and USB signals to swing below ground. This means a common USB and headphone jack can be used for personal media players and portable peripheral devices. Since USB2.0 is an industry standard for shared datapath in portable devices, the FSA223 also incorporates a VCC detection capability. The FSA223 includes a power-off feature to minimize current consumption when VCC is not present. This power-off circuitry is available for the common D+/R, D-/L ports only. Typical applications involve switching in portables and con...
