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 circuitry 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 applications include switching and
connector sharing in portable cell phones, digital
cameras, and notebook computers.
