FSUSB23
Low Power Hi-Speed USB 2.0 (480Mbps) Switch
General Description
Features
The FSUSB23 is a low power high bandwidth analog switch
specifically designed for high speed USB 2.0 applications. The
FSUSB23 features very low quiescent current even when the

control voltage is lower than the V
supply. This feature ser-

vices mobile handset applications well allowing for direct inter-
face with the baseband processor general purpose I/Os. Typical
applications involve switching in portables and consumer appli-
cations such as cell phones, digital cameras, and notebooks
with hubs or controllers. The wide bandwidth (>720MHz) of this

switch exceeds the bandwidth needed to pass the 3 harmonic
which results in signals with minimum edge and phase distor-
tion. Superior channel-to-channel crosstalk results in minimal
interference.

Note 1: The Absolute Maximum Ratings are those values beyond which the safety of
the device cannot be guaranteed. The device should not be operated at these limits.
The parametric values defined in the Electrical Characteristics tables are not guaran-
teed at the absolute maximum rating. The Recommended Operating Conditions
tables will define the conditions for actual device operation.
I/O to GND
Note 2: The input and output negative voltage ratings may be exceeded if the input
and output diode current ratings are observed. DC switch voltage may never exceed
4.6V.
Note 3: Control input must be held HIGH or LOW and it must not float.
