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 (RON) of 1.15

Ω maximum at 4.5V VCC and

4.3

Ω at 2.7V supply. High bandwidth and ultra low (RON)

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.
