Analog Switches | FSA3230

The FSA3230 is a bi-directional, low-power, high-speed, 3:1, USB2.0, MHL™ and audio switch. Configured as a double-pole, triple-throw (DP3T) switch, it is optimized for switching between high- or full-speed USB, Mobile High-Definition Link sources (per MHL Rev. 2.0 specification) and negative swing capable audio. A Single-Pole, Double-Throw (SPDT) switch is provided for ID. This ID switch provides path to support On-The-Go (OTG) communication for the USB Path OR CBUS for the MHL Path.
The FSA3230 contains special circuitry on the switch I/O pins, for applications where the VCC supply is powered off (V_CC=0), 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.
