TS5USBA224 DPDT Multiplexer

Texas Instruments' TS5USBA224 includes a low-distortion audio switch and a USB 2.0 high-speed (480Mbps) switch in the same package.

TS5USBA224 DPDT MultiplexerTexas 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 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.
