ISL54225
High-Speed USB 2.0 (480Mbps) Multiplexer with
Overvoltage Protection (OVP)
ISL54225
The Intersil ISL54225 is a single supply dual 2:1
multiplexer that can operate from a single 2.7V to 5.25V
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 6.5Ω switches were specifically designed to pass
USB high speed/full speed data signals. They have high
bandwidth and low capacitance to pass USB high speed
data signals with minimal DISTORTION.
The ISL54225 has OVP circuitry on the D-/D+ COM pins
that opens the USB in-line switches when the voltage at
these pins exceeds 3.8V (typ) or goes negative by -0.5V
(typ). It isolates fault voltages up to +5.25V or down to
-5V from getting passed to the other-side of the switch,
thereby protecting the USB transceivers.
The digital logic inputs are 1.8V logic compatible when
operated with a 2.7V to 3.6V supply. The ISL54225 has
an output enable pin to open all the switches. It can be
used to facilitate proper bus disconnect and connection
when switching between the USB sources.
The ISL54225 is available in 10 Ld 1.8mmx1.4mm
TQFN and 10 Ld TDFN packages. It operates over a
temperature range of -40°C to +85°C.
