Description
The FSA110 is a Double-Pole, Single Throw (DPST) switch that combines a low-distortion audio path with low off capacitance for USB applications. This configuration is ideal for wired-OR configurations, enabling shared USB2.0 Hi-Speed (HS) and audio on a single connector. The architecture is designed to allow audio signals to swing below ground so a common USB and headphone jack can be used for personal media players and portable peripheral devices.

FEATUREs
■ 6pF Typical Switch Off Capacitance for HS USB
■ 2.5Ω Typical On Resistance for Audio Signaling
■ Negative-Swing-Capable Audio Channel
■ Automatic USB Detection Available
■ Power-Off Protection on the D+/R, D-/L Ports
■ Flow-Through Pin Out Eliminates PCB Vias
■ Built-In Termination on Unselected Audio Paths Inhibits Audio Pop

APPLICATIONs
■ Cell Phone, PDA, Digital Camera, and Notebook
■ LCD Monitor, TV, and Set-Top Box
