简介
The 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 Single Pole/Double Throw (SPDT) 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 7Ω normally-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 4.5Ω 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 full-speed transceiver while connected to a single USB host (computer). The digital logic inputs are 1.8V logic compatible when operated with a 2.7V to 3.6V supply. The part has an enable pin to open all switches. It can be used to facilitate proper bus disconnect and connection when switching between the USB sources. The ISL54200 is available in a 10 Ld 3mm x 3mm TDFN and a small 10 Ld 2.1mm x 1.6mm µTQFN package. It operates over a temperature range of -40 °C to +85 °C.
