FSUSB11
Low Power High Bandwidth USB Switch
Dual SPDT Multiplexer/Demultiplexer
General Description
Features
■ Space saving MicroPak packaging (1.6mm x 2.1mm)
■ USB 1.1 signal switching compliant
■ −3db bandwidth: >350MHz
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 1.3Ω maximum
■ Maximum 1.15Ω ON Resistance at 4.5V VCC
and 4Ω for 2.7V supply
at 4.5V VCC and 4.3Ω at 2.7V supply. High bandwidth and
ultra low ON Resistance (RON) make this switch to be able
■ 0.3Ω maximum RON flatness for +5V supply
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.
■ Broad VCC operating range: 1.65V to 5.5V
■ Fast turn-on and turn-off time
■ Break-before-make enable circuitry
■ Over-voltage tolerant TTL compatible control input

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 4: ON Resistance is determined by the voltage drop between D and Dn pins at the indicated current through the switch.
Note 5: ∆RON = RONmax − RONmin measured at identical VCC, temperature, and voltage.
Note 6: Flatness is defined as the difference between the maximum and minimum value of ON Resistance over the specified range of conditions.
