Overview

The ISL54222A is a single supply dual 2:1 multiplexer that can operate from a single 1.8V to 3.3V supply. It contains two Single Pole/Double Throw (SPDT) 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 4.4Ω 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 with a single supply as low as 1.8V. 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 1.8V to 3.3V supply. The ISL54222A has an output enable pin to open all the switches and put the part in a low power state. The ISL54222A is available in 10 Ld 1.8mm x 1.4mm µTQFN, 10 Ld 2.1mm x 1.6mm µTQFN, 10 Ld TDFN and 10 Ld MSOP packages. It operates over a temperature range of -40 °C to +85 °C.
