In addition when VDD is at 0V (ground) all switches are OFF
and the shorted VBUS voltage is isolated from the other side
of the switch. When VDD is in the range of 2.7V to 5.5V the
shorted VBUS voltage will pass through to the output of an
active (turned ON) switch channel but not through a turned
OFF channel. Any components connected on the active
channel must be able to withstand the overvoltage condition.
Note: During the fault condition normal operation of the USB
channel is not guaranteed until the fault condition is
removed.
Typical Performance Curves TA = +25°C, Unless Otherwise Specified
