ISL54221
High-Speed USB 2.0 (480Mbps)
Multiplexer
The Intersil ISL54221 is a single supply dual 2:1 multiplexer
that can operate from a single 2.7V to 5.5V 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 6.7
Ω 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. 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 2.7V to 3.6V supply. The ISL54221 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 ISL54221 is available in a tiny 10 Ld 2.1mmx1.6mm
TQFN package. It operates over a temperature range of
-40 to +85°C.
