FSUSB20 — Low-Power, 1-Port, High-Speed USB  
(480Mbps) Switch  
Features  
Description  
FSUSB20 is  
a
low-power, high-bandwidth switch  
.
.
.
.
.
.
.
.
-30dB Off Isolation: 250MHz  
specially designed for switching high-speed USB 2.0  
signals in handset and consumer applications; such as  
cell phone, digital camera, and notebook with hubs or  
controllers of limited USB I/O. The wide bandwidth  
(>720MHz) allows signals to pass with minimum edge  
and phase distortion. Superior channel-to-channel  
crosstalk results in minimal interference. It is compatible  
with the high-speed USB 2.0 standard.  
-30dB Non-adjacent Channel Crosstalk: 250MHz  
On Resistance: 4.5Ω Typical (RON)  
-3dB Bandwidth: >720MHz  
Low-Power Consumption: 1µA Maximum  
Control Input: LVTTL Compatible  
Bi-Directional Operation

Absolute Maximum Ratings  
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.

Recommended Operating Conditions  
The Recommended Operating Conditions table defines the conditions for actual device operation. Recommended  
operating conditions are specified to ensure optimal performance to the datasheet specifications. Fairchild does not  
recommend exceeding them or designing to Absolute Maximum Ratings.

3. Measured by the voltage drop between the A and B pins at the indicated current through the switch. On  
resistance is determined by the lower of the voltages on the A or B pins.  
4. Flatness is defines as the difference between the maximum and the minimum value on resistance over the  
specified range of conditions.
