Manufacturer
INTERSIL [Intersil Corporation]
Datasheet
High-Speed USB 2.0 (480Mbps) Multiplexer with
Overvoltage Protection (OVP) and Overvoltage
Indicator Output
ISL54224
The Intersil ISL54224 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 of USB data 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 ISL54224 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 ISL54224 has
an open drain OE/ALM pin that can be driven Low to
open all switches and outputs a Low when the OVP
circuitry is activated. It can be used to facilitate proper
bus disconnect and connection when switching between
the USB sources.
The ISL54224 is available in 10 Ld 1.8mmx1.4mm
µTQFN and 10 Ld TDFN packages. It operates over a
temperature range of -40 to +85°C.
