FN6836.0
High-Speed USB 2.0 (480Mbps)
Multiplexer
The Intersil ISL54223 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 5.5Ω 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 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 part can be used in Personal Media Players and other
portable battery powered devices that need to route USB
high-speed signals and/or full-speed signals to different
transceiver sections of the device while connected to a single
USB host (computer).
The digital logic inputs are 1.8V logic compatible when
operated with a 1.8V to 3.3V supply. The ISL54223 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 ISL54223 is available in a 10 Ld 2.1mmx1.6mm µTQFN
package. It operates over a temperature range of -40 to +85°C.

NOTES:
2. Signals on HSD1x, HSD2x, D+, D- exceeding GND by specified amount are clamped. Signals on OE and SEL exceeding VDD or GND by
specified amount are clamped. Limit current to maximum current ratings.
3. θJA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
