Description December 2009 The FSUSB43 is a bi-directional, low-power, two-port, high-speed, USB2.0 switch. Configured as a doublepole, double-throw (DPDT) switch, it is optimized for switching between two high-speed (480Mbps) sources or a high-speed and full-speed (12Mbps) source. The FSUSB43 is compatible with the requirements of USB2.0 and features an extremely low on capacitance (C ON) of 3.7pF. The wide bandwidth of this device (720MHz) exceeds the bandwidth needed to pass the third harmonic, resulting in signals with minimum edge and phase distortion. Superior channel-to-channel crosstalk also minimizes interference. The FSUSB43 contains special circuitry on the switch I/O pins for applications where the V CC supply is powered-off (V CC=0), which allows the device to withstand an over-voltage condition. This minimizes current consumption even when the control voltage applied to the SEL pin is lower than the supply voltage (V CC). This feature is especially valuable to mobile applications, such as cell phones, allowing for direct interface with the general-purpose I/Os of the baseband processor. Other applications include switching and connector sharing in portable cell phones, PDAs, digital cameras, printers, and notebook computers. HSD1+ HSD2+ D+ HSD1- HSD2- Sel Control D- /OE Figure 1.

3 Absolute Maximum Ratings 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 is 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. Symbol Parameter Min. Max.
