DESCRIPTION
The TS5USBA224 is a double-pole, double throw (DPDT) multiplexer that includes a low-distortion audio switch
and a USB 2.0 High-Speed (480Mbps) switch in the same package. This configuration allows the system
designer to use a common connector for audio and USB data. The audio switch is designed to allow audio
signals to swing below ground which makes this common connector configuration possible.
The TS5USBA224 is powered up using V_AUDIO. When A_SEL=High, the audio path is selected regardless of the
logic level at V_BUS. If A_SEL=Low and V_BUS=High, the USB path is selected. Otherwise if A_SEL=Low and V_BUS=Low,
the audio path is selected.
The TS5USBA224 also features shunt resistors on the audio path to reduce clicks and pops that may be heard
when the audio switches are selected.
