USB 2.0 High/Full Speed Multiplexer  
Features  
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.  
• High Speed (480Mbps) and Full Speed (12Mbps)  
Signaling Capability per USB 2.0  
• 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

DD  
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).  
• Available in Ultra-thin µTQFN and TDFN Packages  
• Pb-Free Plus Anneal Available (RoHS Compliant)  
Applications  
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.  
• MP3 and other Personal Media Players  
• Cellular/Mobile Phones  
• PDA’s  
• Digital Cameras and Camcorders  
The ISL54200 is available in a 10 Ld 3mmx3mm TDFN and a  
small 10 Ld 2.1mmx1.6mm µTQFN packages. It operates  
over a temperature range of -40 to +85°C.
