USB 2.0 High/Full Speed Multiplexer

ISL54200

The Intersil 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 SPDT (Single Pole/Double

Throw) 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.

rail-to-rail and were specifically designed to pass USB

full speed data signals (12Mbps) that range from 0V to

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 3mmx3mm TDFN

and a small 10 Ld 2.1mmx1.6mm µTQFN package. It

operates over a temperature range of -40°C to +85°C.
