February 4, 2010 High-Speed USB 2.0 (480Mbps) Multiplexer
The Intersil ISL54222A is a single supply dual 2:1
multiplexer that can operate from a single 1.8V to
3.3V 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 4.4пЃ—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 highspeed data signals that range from 0V to 400mV with
a single supply as low as 1.8V. They have high
bandwidth and low capacitance to pass USB high
speed data signals with minimal distortion.
The digital logic inputs are 1.8V logic compatible when
operated with a 1.8V to 3.3V supply. The ISL54222A
has an output enable pin to open all the switches and
put the part in a low power state.
The ISL54222A is available in 10 Ld 1.8mmx1.4mm
