SuperSpeed USB Passive Switch
(Low/Full/Hi/SuperSpeed)
5
Note 2: All devices are 100% production tested at T
A
= +25NC. All temperature limits are guaranteed by design.
Note 3: The switch turns off for voltages above V
FP
, protecting downstream circuits in case of a fault condition.
Note 4: DR

Note 5: Guaranteed by design. Not production tested.
Note 6: Flatness is defined as the difference between the maximum and minimum value of on-resistance, as measured over spec-
ified analog-signal ranges.
Note 7: Between any two switches.
