Description

The FSA3341 is a bi-directional, low-power, high-speed, 4:1, USB2.0 and MHL™ switch. 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, the USB2.0 paths can be used as UART paths. The FSA3341 contains circui try on the switch I/O pins that allows the device to withstand an over-voltage condition for applications where the V CC supply is powered off (V CC = 0 V). 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 applicatio ns include switching and connector sharing in portable cell phones, digital cameras, and notebook computers.
