Description
The FSUSB11 is a high-performance, dual Single-Pole
Double-Throw (SPDT) switch designed for switching
USB 1.1 signals. The device features ultra-low on
resistance (R
ON
) of 1.15Ω maximum at 4.5V V
CC
and
4.3Ω at 2.7V supply. High bandwidth and ultra low (R
ON
)
make this switch 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 designed for break-
before-make operation. The select input is TTL-level
compatible.
