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 R_ON of 1.3Ω maximum
at 4.5V V_CC and 4.3Ω at 2.7V supply. High bandwidth and
ultra low ON Resistance (R_ON) 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.
