The Intersil ISL54220 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 6.7Ω switches can swing rai-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).
