DATASHEET ISL54221 FN6820 Rev 0.00 High-Speed USB 2.0 (480Mbps) Multiplexer December 16, 2008 The Intersil ISL54221 is a single supply dual 2:1 multiplexer Features that can operate from a single 2.7V to 5.5V supply. It contains High-Speed (480Mbps) and Full-Speed (12Mbps) two SPDT (Single Pole/Double Throw) switches configured as Signaling Capability per USB 2.0 a DPDT. The part was designed for switching or routing of USB High-Speed signals and/or USB Full-speed signals in 1.8V Logic Compatible (2.7V to +3.6V supply) portable battery powered products. Enable Pin to Open all Switches The 6.7switches can swing rail to rail and were specifically Power OFF Protection designed to pass USB full-speed data signals that range from D-/D+ Pins Overvoltage Tolerant to 5.5V 0V to 3.3V and USB high-speed data signals that range from 0V to 400mV. They have high bandwidth and low capacitance -3dB Frequency 742MHz to pass USB high-speed data signals with minimal distortion. Low ON Capacitance 7.4pF The part can be used in Personal Media Players and other Low ON-Resistance 6.7 portable battery powered devices that need to route USB Single Supply Operation (V ) . 2.7V to 5.5V high-speed signals or full-speed signals to different DD transceiver sections of the device while connected to a single Available in TQFN Package USB host (computer). Pb-Free (RoHS Compliant) The digital logic inputs are 1.8V logic compatible when Compliant with USB 2.0 Short Circuit and Overvoltage operated with a 2.7V to 3.6V supply. The ISL54221 has an Requirements Without Additional External Components output enable pin to open all the switches. It can be used to facilitate proper bus disconnect and connection when Applications switching between the USB sources. MP3 and other Personal Media Players The ISL54221 is available in a tiny 10 Ld 2.1mmx1.6mm Cellular/Mobile Phones TQFN package. It operates over a temperature range of -40 to +85C.
