February 4, 2010 High-Speed USB 2.0 (480Mbps) Multiplexer
The Intersil ISL54220 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.
The 6пЃ—пЂ 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. Features High-Speed (480Mbps) and Full-Speed (12Mbps)
