USB 2.0 High/Full Speed Multiplexer
FN6408 Rev 2.00 June 17, 2010
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 7normally-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 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 fullspeed transceiver while connected to a single USB host (puter).
