High-Speed USB 2.0 (480Mbps) Multiplexer
ISL54220
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 6Ω 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.
The digital logic inputs are 1.8V logic compatible when
operated with a 2.7V to 3.6V supply. The ISL54220 has
an output enable pin to open all the switches.
The ISL54220 is available in 10 Ld 1.8mmx1.4mm
µTQFN, 10 Ld TDFN and 10 Ld MSOP packages. It
operates over a temperature range of -40 to +85°C.
