FSA3341: High-Speed 4:1 USB2.0 / Mobile High-Definition Link (MHL™) Switch

The FSA3341 is a bi-directional, low-power, high-speed, 4:1, USB2.0 and MHL™. Configured as a Double-Pole, Four-Throw (DP4T) switch; it is optimized for switching between high- or full-speed USB and Mobile High-Definition Link sources (MHL Rev. 2.0 specification). In addition, either USB 2.0 path can be used as a UART paths.

The FSA3341 contains circuitry on the switch I/O pins, for applications where the VCC supply is powered off (VCC = 0 V), that allows the device to withstand an over-voltage condition. This switch is designed to minimize current consumption even when the control voltage applied to the control pins is lower than the supply voltage (VCC). This is especially valuable in mobile applications, such as cell phones, allowing direct interface with the general-purpose I/Os of the baseband processor. Other applications include switching and connector sharing in portable cell phones, digital cameras, and notebook computers.
