High-Speed USB 2.0 (480Mbps)
Multiplexer
The Intersil ISL54222A 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 5.7Ω 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 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 ISL54222A has an
output enable pin to open all the switches and puts the part in
a low power state. It can be used to facilitate proper bus
disconnect and connection when switching between the USB
sources.
The ISL54222A is available in 10 Ld 1.8mmx1.4mm µTQFN,
10 Ld 2.1mmx1.6mm µTQFN, 10 Ld TDFN and 10Ld MSOP
packages. It operates over a temperature range of -40° to
+85°C.
