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 VAUDIO. When ASEL=High, the audio path is selected regardless of the

logic level at VBUS. If ASEL=Low and VBUS=High, the USB path is selected. Otherwise if ASEL=Low and VBUS=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.
