Description
The FSUSB73 is a bi-directional, low-power, high-speed
USB 2.0 3:1 MUX plus one isolation switch. It is optimized
for switching three high-speed (480Mbps) or full / low-speed
USB / UART sources to one USB 2.0 connector. In addition,
the FSUSB73 has an integrated routing USB switch to allow
communication between a USB hub and another processor
without re-enumeration.
