TS5USBA224 DPDT Multiplexer

Texas Instruments' TS5USBA224 is a double-pole, double throw (DPDT) multiplexer that includes a low-distortion audio switch and a USB 2.0 high-speed (480 Mbps) 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.
