ISL54222IRUZ-T

Manufacturer Part Number
ISL54222IRUZ-T
Description
High-Speed USB 2.0 (480Mbps) Multiplexer
Manufacturer
INTERSIL [Intersil Corporation]
Datasheet
High-Speed USB 2.0 (480Mbps)
Multiplexer
The Intersil ISL54222 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 ISL54222 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 ISL54222 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.
