Analog Switch Single DPDT 10-Pin MSOP T/R

The FSA221 is a Double-Poe, Double Throw (DPDT) multiplexer that combines a low-distortion audio and a USB2.O High-speed (HS) switch path. This configuration enables audio and USB data to share a common connector port. The architecture is designed to allow audio 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.O is an industry standard for shared data- path in portable devices, the FSA221 also incorporates a detection capability. The FSA221 includes a power-off feature to minimize current consumption when 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 "the hubs or controllers.
