Data Sheet  
December 16, 2008  
FN6820.0  
High-Speed USB 2.0 (480Mbps)  
Multiplexer  
Features  
• High-Speed (480Mbps) and Full-Speed (12Mbps)  
Signaling Capability per USB 2.0  
The Intersil ISL54221 is a single supply dual 2:1 multiplexer  
that can operate from a single 2.7V to 5.5V supply. It contains  
two SPDT (Single Pole/Double Throw) switches configured as  
a DPDT. The part was designed for switching or routing of  
USB High-Speed signals and/or USB Full-speed signals in  
portable battery powered products.  
• 1.8V Logic Compatible (2.7V to +3.6V supply)  
• Enable Pin to Open all Switches  
• Power OFF Protection  
• D-/D+ Pins Overvoltage Tolerant to 5.5V  
The 6.7Ω switches can swing rail to rail and were specifically  
designed to pass USB full-speed data signals that range from  
0V to 3.3V and USB high-speed data signals that range from  
0V to 400mV. They have high bandwidth and low capacitance  
to pass USB high-speed data signals with minimal distortion.  
• -3dB Frequency . . . . . . . . . . . . . . . . . . . . . . . . . . 742MHz  
• Low ON Capacitance. . . . . . . . . . . . . . . . . . . . . . . . 7.4pF  
• Low ON-Resistance. . . . . . . . . . . . . . . . . . . . . . . . . . 6.7Ω  
• Single Supply Operation (V ) . . . . . . . . . . . . 2.7V to 5.5V  
DD  
The part can be used in Personal Media Players and other  
portable battery powered devices that need to route USB  
high-speed signals or full-speed signals to different  
transceiver sections of the device while connected to a single  
USB host (computer).  
• Available in µTQFN Package  
• Pb-Free (RoHS Compliant)  
• Compliant with USB 2.0 Short Circuit and Overvoltage  
Requirements Without Additional External Components  
The digital logic inputs are 1.8V logic compatible when  
operated with a 2.7V to 3.6V supply. The ISL54221 has an  
output enable pin to open all the switches. It can be used to  
facilitate proper bus disconnect and connection when  
switching between the USB sources.  
Applications  
• MP3 and other Personal Media Players  
• Cellular/Mobile Phones  
• PDA’s  
The ISL54221 is available in a tiny 10 Ld 2.1mmx1.6mm  
µTQFN package. It operates over a temperature range of  
-40 to +85°C.  
• Digital Cameras and Camcorders  
• USB Switching
