USB 2.0 High/Full Speed Multiplexer  
ISL54200  
Features  
• High Speed (480Mbps) and Full Speed (12Mbps)  
Signaling Capability per USB 2.0  
The Intersil ISL54200 dual 2:1 multiplexer IC is a single  
supply part 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 between USB High-Speed and  
USB Full-Speed sources in portable battery powered  
products.  
• 1.8V Logic Compatible (2.7V to +3.6V supply)  
• Enable Pin to Open all Switches  
• -3dB Frequency  
- HSx Switches. . . . . . . . . . . . . . . . . . . . .880MHz  
- FSx Switches . . . . . . . . . . . . . . . . . . . . .550MHz  
The 7Ω normally-closed (NC) FSx switches can swing  
rail-to-rail and were specifically designed to pass USB  
full speed data signals (12Mbps) that range from 0V to  
3.6V. The 4.5Ω normally-open (NO) HSx switches have  
high bandwidth and low capacitance and were  
specifically designed to pass USB high speed data  
signals (480Mbps) with minimal distortion.  
• Crosstalk @ 1MHz . . . . . . . . . . . . . . . . . . -70dB  
• Off Isolation @ 100kHz . . . . . . . . . . . . . . . -98dB  
• Single Supply Operation (V ) . . . . . 2.7V to 5.5V  
DD  
• Available in Ultra-thin µTQFN and TDFN Packages  
• Pb-Free (RoHS Compliant)  
The part can be used in Personal Media Players and  
other portable battery powered devices that need to  
switch between a high-speed transceiver and a full-  
speed transceiver while connected to a single USB host  
(computer).  
Applications*(see page 16)  
• MP3 and other Personal Media Players  
• Cellular/Mobile Phones  
• PDA’s  
The digital logic inputs are 1.8V logic compatible when  
operated with a 2.7V to 3.6V supply. The part has an  
enable pin to open all switches. It can be used to  
facilitate proper bus disconnect and connection when  
switching between the USB sources.  
• Digital Cameras and Camcorders

Technical Brief TB363 “Guidelines for Handling and  
Processing Moisture Sensitive Surface Mount Devices  
(SMDs).  
The ISL54200 is available in a 10 Ld 3mmx3mm TDFN  
and a small 10 Ld 2.1mmx1.6mm µTQFN package. It  
operates over a temperature range of -40°C to +85°C.
