ISL54200
USB 2.0 High/Full Speed Multiplexer
The Intersil ISL54200 dual 2:1 multiplexer IC is a single
supply part 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
between USB High-Speed and USB Full-Speed sources in
portable battery powered products.
The 7
Ω
normally-closed (NC) FSx switches can swing rail to
rail and were specifically designed to pass USB full speed
data signals (12Mbps) that range from 0V to 3.6V. The 4.5
Ω
normally-open (NO) HSx switches have high bandwidth and
low capacitance and were specifically designed to pass USB
high speed data signals (480Mbps) with minimal distortion.
The part can be used in Personal Media Players and other
portable battery powered devices that need to switch between
a high-speed transceiver and a full-speed transceiver 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 part has an enable
pin to open all switches. It can be used to facilitate proper bus
disconnect and connection when switching between the USB
sources.
The ISL54200 is available in a 10 Ld 3mmx3mm TDFN and a
small 10 Ld 2.1mmx1.6mm μTQFN packages. It operates
over a temperature range of -40 to +85°C.
