The USB switches are bi-directional, which allows the host
(computer) and downstream USB device to both send and
receive data.
Full-Speed Switches
The two FSx switches (FSD1, FSD2) are bi-directional
switches that can pass rail-to-rail signals. When powered
with a 3.3V supply, these switches have a nominal r
resistance of 7Ω over the signal range of 0V to 3.3V. They
were specifically designed to pass USB full-speed (12Mbps)
differential signals and meet the USB 2.0 full-speed signal
quality specifications.
The FSx switches can also pass USB high speed signals
(480Mbps) but do not quite meet the USB 2.0 high speed
signal quality eye diagram compliance requirement.
The maximum signal range for the FSx switches is from
-1.5V to V
exceed the V
than -1.5V.
When operated with a 3.3V to 3.6V supply, the FSx switches
are active (turned ON) whenever the IN logic control voltage
is
High-Speed Switches
The two HSx switches (HSD2, HSD1) are bi-directional
switches that can pass rail-to-rail signals. When powered
with a 3.3V supply, these switches have a nominal r
4.5Ω over the signal range of 0V to 400mV with a r
flatness of 0.4Ω. The r
HSD2 switches over this signal range is only 0.01Ω ensuring
minimal impact by the switches to USB high speed signal
transitions. As the signal level increases, the r
resistance increases. At signal level of 3.3V the switch
resistance is nominally 20Ω.

of
The HSx switches were specifically designed to pass USB
2.0 high-speed (480Mbps) differential signals typically in the
range of 0V to 400mV. They have low capacitance and high
bandwidth to pass the USB high-speed signals with
minimum edge and phase distortion to meet USB 2.0 high
speed signal quality specifications.
The HSx switches can also pass USB full-speed signals
(12Mbps) with minimal distortion and meet all the USB
requirements for USB 2.0 full-speed signaling.
The maximum signal range for the HSx switches is from
-1.5V to V
voltage rail or go below ground by more than -1.5V.
The HSx switches are active (turned ON) whenever the IN
voltage is
operated with a 3.3V to 3.6V supply.
