Automotive Grade USB 2.0 High/Full  
Speed Multiplexer  
Features  
• High Speed (480Mbps) and Full Speed (12Mbps)  
Signaling Capability per USB 2.0  
The Intersil ISL76120 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, Simplifies Multiple USB  
Client Management  
• -3dB Frequency  
- HSx Switches. . . . . . . . . . . . . . . . . . . . . . . . . . . . . 880MHz  
- FSx Switches. . . . . . . . . . . . . . . . . . . . . . . . . . . . . 550MHz  
The 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 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

• Available in TDFN Package  
• Robust ESD rating > 8.5kV HBM  
• Ultra-Low Operating Current - 60nA  
• -40°C to 105°C Operation  
The part can be used in a variety of automotive entertainment  
and infotainment applications where consumer USB devices  
such as Portable Media Players (PMPs) are to be connected  
to embedded systems. The product allows switching between  
a high-speed transceiver and a full-speed transceiver while  
connected to a single USB host. Additionally the part can be  
used for charge control of PMPs.  
• AECQ100 Qualified Component  
• Pb-Free (RoHS Compliant)  
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.  
Applications  
• Automotive  
- USB Docks  
- MP3 and PMP Player Attach Kits  
- Infotainment Systems  
The ISL76120 is available in a 10 Ld 3mm x 3mm TDFN  
package. It operates over a temperature range of -40°C to  
+105°C.
