ISL54220 High-Speed USB 2.0 (480Mbps) Multiplexer

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 6Ω 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 digital logic inputs are 1.8V logic compatible when operated with a 2.7V to 3.6V supply. The ISL54220 has an output enable pin to open all the switches. The ISL54220 is available in 10 Ld 1.8mmx1.4mm μTQFN, 10 Ld TDFN and 10 Ld MSOP packages. It operates over a temperature range of -40°C to +85°C.
