Fairchild Semiconductor FSUSB42
The FSUSB42 is a bi-directional, low-power, two-port, high-speed, USB2.0 switch. The FSUSB42 is compatible with the requirements of USB2.0 and features an extremely low on capacitance (CON) of 3.7 pF. The wide bandwidth of this device (720 MHz) exceeds the bandwidth needed to pass the third harmonic, resulting in signals with minimum edge and phase distortion.| Part No. | FSUSB42 |

DESCRIPTION
Configured as a doublepole, double-throw switch (DPDT) switch, it is optimized for switching between any combination of high-speed (480 Mbps) or Full-Speed (12 Mbps) sources. Superior channel-to-channel crosstalk also minimizes interference. The FSUSB42 contains special circuitry on the switch I/O pins for applications where the VCC supply is powered-off (VCC=0 V), 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 SEL pin is lower than the supply voltage (VCC).
