FSUSB11: Low Power Full Speed USB Switch

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 1.3Ω maximum at 4.5V VCC and 4.3Ω at 2.7V supply. High bandwidth and ultra-low on resistance (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 is designed for break-before-make operation. The select input is TTL level compatible.
