Analog Switches | FSA3341

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 V_CC supply is powered off (V_CC = 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 (V_CC). 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.
