DESCRIPTION
The TS3USBA225 is a double-pole, triple throw (DP3T) multiplexer that includes a low-distortion audio switch,
and two USB 2.0 High-Speed (480Mbps) switches 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 negatively which makes this common connector configuration possible.
The TS3USBA225 has a VCC range of 2.7V to 4.3V with the capability to pass true-ground audio signals down
to Vcc-4.3V. The device also supports a power-down mode that can be enabled when both SEL controls are low
to minimize current consumption when no signal is transmitting. The TS3USBA225 also features internal shunt
resistors on the audio path to reduce clicks and pops that may be heard when the audio switches are selected.
