The FSUSB23 is a low-power, high-bandwidth analog
switch specifically designed for high speed USB 2.0
applications. The FSUSB23 features very low quiescent
current even when the control voltage is lower than the
VCC supply. This feature services mobile handset
applications, allowing direct interface with the baseband
processor general-purpose I/Os.
Lower Capacitance: CON = 9pF Typical
7Ω Typical On Resistance (RON)
-3dB Bandwidth: > 720MHz
Typical applications involve switching in portables and
consumer applications, such as cell phones, digital
cameras, and notebooks with hubs or controllers. The
wide bandwidth (>720MHz) of this switch exceeds the
bandwidth needed to pass the third harmonic, which
results in signals with minimum edge and phase
distortion. Superior channel-to-channel crosstalk results
in minimal interference.
Low Power Consumption: 1mA Maximum
Wide -3db Bandwidth: > 720MHz

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device
reliability. The absolute maximum ratings are stress ratings only.
