Low On Capacitance: 3.7pF Typical
The FSUSB43 is a bi-directional, low-power, two-port,
high-speed, USB2.0 switch. Configured as a doublepole, double-throw (DPDT) switch, it is optimized for
switching between two high-speed (480Mbps) sources
or a high-speed and full-speed (12Mbps) source.
Low On Resistance: 3.9Ω Typical
Low Power Consumption: 1μA Maximum
- 20μA Maximum ICCT over an Expanded Voltage
Range (VIN=1.8V, VCC=4.3V)

The FSUSB43 is compatible with the requirements of
USB2.0 and features an extremely low on capacitance
(CON) of 3.7pF. The wide bandwidth of this device
(720MHz) exceeds the bandwidth needed to pass the
third harmonic, resulting in signals with minimum edge
and phase distortion. Superior channel-to-channel
crosstalk also minimizes interference.
The FSUSB43 contains special circuitry on the switch
I/O pins for applications where the VCC supply is
powered-off (VCC=0), which allows the device to
withstand an over-voltage condition. This minimizes
current consumption even when the control voltage
applied to the SEL pin is lower than the supply voltage
(VCC). This feature is especially valuable to mobile
applications, such as cell phones, allowing for direct
interface with the general-purpose I/Os of the baseband
processor. Other applications include switching and
connector sharing in portable cell phones, PDAs, digital
cameras, printers, and notebook computers.
