FSUSB31
Low Power Dual SPST Hi-Speed USB 2.0 (480Mbps)
Switch
Features
General Description
■ Low On capacitance, 6.0pF (typical)
The FSUSB30 is a Low Power, Dual SPST 2-Port
Hi-Speed USB 2.0 switch. This part is configured as a
single pole, single throw switch and is optimized for
switching or isolating a Hi-Speed (480Mbps) source or a
Hi-Speed and Full Speed (12Mbps) source. The
FSUSB31 is compatible with the requirements of USB2.0
and features an extremely low On Capacitance (CON) of
6.0pF. The wide bandwidth of this device (>720MHz),
exceeds the bandwidth needed to pass the 3rd harmonic,
resulting in signals with minimum edge and phase distortion. Superior channel-to-channel crosstalk also minimizes interference.
■ Low On resistance, 6.5Ω (typical)
■ Low power consumption (1µA maximum)
■
■
■
■
– 10µA maximum ICCT over and expanded control
voltage range (VIN = 2.6V, VCC = 4.3V)
Wide -3dB bandwidth, > 720MHz
8K I/O to GND ESD protection
Power OFF protection when VCC = 0V, D+ / D- pins can
tolerate up to 4.3V
Packaged in:
– Pb-Free 8-lead MicroPak™ (1.6mm x 1.6mm)
– Pb-Free 8-lead US-8 (preliminary)
The FSUSB31 contains special circuitry on the D+ / Dpins which allows the device to withstand an overvoltage
condition. This device is also designed to minimize current consumption even when the control voltage applied
to the OE pin, is lower than the supply voltage (VCC). This
feature is especially valuable to Ultra-Portable applications such as cell phones, allowing for direct interface
with the General Purpose I/Os of the baseband processor. Other applications include port isolation and switching in portable cell phones, PDAs, digital cameras,
printers, and notebook computers.
Applications
■ Cell phone, PDA, Digital Camera, and Notebook
■ LCD Monitor, TV, and Set-top Box

The “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed.
The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics
tables are not guaranteed at the absolute maximum ratings. The “Recommended Operating Conditions” table will
