FSUSB11
Low Power High Bandwidth USB Switch
Dual SPDT Multiplexer/Demultiplexer
General Description
The FSUSB11 is a high performance Dual Single Pole
Double Throw (SPDT) analog switch specially designed for
the switching of both analog audio signal and USB 1.1 sig-
nals. The device features ultra low RON of 1.3maximum
at 4.5V VCC and 4.3at 2.7V supply. High bandwidth and
ultra low ON Resistance (RON) make this switch to be able
to pass both USB low and full speed signal with minimum
signal distortion. The device is fabricated with sub-micron
CMOS technology to achieve fast switching speeds and is
designed for break-before-make operation. The select
input is TTL level compatible.

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 guaranteed at the absolute maximum ratings.
The “Recommended Operating Conditions” table will define the conditions
for actual device operation.
Note 2: The input and output negative voltage ratings may be exceeded if
the input and output diode current ratings are observed.
Note 3: Unused inputs must be held HIGH or LOW. They may not float.
