ISL54222A

High-Speed USB 2.0 (480Mbps) Multiplexer

FN6902

Rev 1.00

February 4, 2010

The Intersil ISL54222A is a single supply dual 2:1

multiplexer that can operate from a single 1.8V to

3.3V 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.

Features

• High-Speed (480Mbps) and Full-Speed (12Mbps)

Signaling Capability per USB 2.0

• 1.8V Logic Compatible

• Low Power All Off State

• Power OFF Protection

The 4.4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.

• D-/D+ Pins Overvoltage Tolerant to 5.5V

• -3dB Frequency. . . . . . . . . . . . . . . . . . . 780MHz

• Low ON Capacitance @ 240MHz . . . . . . . . 4.2pF

• Low ON-Resistance @ V

= 3V . . . . . . . . . 4.4

= 1.8V. . . . . . . . 5.7

• Single Supply Operation (V ) . . . . . 1.8V to 3.3V

• Available in µTQFN, TDFN, MSOP Packages

• Pb-Free (RoHS Compliant)

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.

• Compliant with USB 2.0 Short Circuit and

Overvoltage Requirements Without Additional

External Components

The ISL54222A is available in 10 Ld 1.8mmx1.4mm

µTQFN, 10 Ld 2.1mmx1.6mm µTQFN, 10 Ld TDFN and

10 Ld MSOP packages. It operates over a temperature

range of -40° to +85°C.

• HBM ESD Performance I/O to GND . . . . . >12kV

Applications*(see page 15)

• MP3 and other Personal Media Players

• Cellular/Mobile Phones

• PDAs
