FSA223 Datasheet PDF - ON Semiconductor

●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 data-path in portable devices, the FSA223 also incorporates a V detection capability. The FSA223 includes a power-off feature to minimize current consumption when V 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 consumer applications, such as cell phones, digital cameras, and notebooks with hubs or controllers
