FSA3041 High-Speed 4:1 USB2.0 / MHL™ / Audio / UART Switch Description Features  Low On Capacitance: 4.2 pF / 7.5 pF MHL / USB (Typical)        Low Power Consumption: 30 μA Maximum Supports MHL Rev. 2.0 MHL Data Rate: 3.8 Gbps LINOUT Swing: -1.5 V to +3.0 V (Typical) USB 2.0 Compliant Packaged in 16-Lead UMLP (1.8 x 2.6 mm) Over-Voltage Tolerance on All USB Ports: Up to 5.25 V without External Components Applications   Cell Phones Digital Cameras The FSA3041 is a bi-directional, low-power, high-speed, 4:1, USB2.0, MHL™, UART, and audio switch. Configured as a Double-Pole, Four-Throw (DP4T) switch; it is optimized for switching between high- or fullspeed USB, Mobile High-Definition Link sources (MHL Rev. 2.0 specification), UART, and negative-swing capable audio. In addition, either USB 2.0 path can be used as a UART path. The FSA3041 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 overvoltage 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.

To guarantee default switch closure to the USB position, the SEL[0:1] pins are tied to GND with internal weak pull-down resistors (3MΩ) to minimize static current draw. www.fairchildsemi.com 2 Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels i s not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only.
