Description The FSUSB46 is a bi-directional, low-power, Hi-Speed, USB2.0 switch. onfigured as a double-pole, singlethrow switch (DPST) switch, it is optimized for switching a Hi-Speed (480Mbps) source. The FSUSB46 is compatible with the requirements of USB2.0 and features an extremely low on capacitance ( ON ) of 3.9pF. 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 FSUSB46 contains special circuitry on the switch I/O pins for applications where the V supply is powered-off (V =0), which allows the device to withstand an over-voltage condition. This device is designed to minimize current consumption even when the control voltage applied to the pin is lower than the supply voltage (V ). This feature is especially valuable to ultra-portable applications, such as cell phones, allowing for direct interface with the generalpurpose I/Os of the baseband processor. An additional feature is the detection of the 1-1 (high/high) state on D+/D- to signal an interrupt (INT) to the processor when entering a dedicated charging port mode of operation.

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.
