Rev 0.00
July 2, 2010 High-Speed USB 2.0 (480Mbps) Multiplexer with Overvoltage Protection (OVP)
The 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 6.5пЃ—пЂ 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 …
