Small size High-ESD withstanding USB 2.0 multiplexer operates from 1.8V

This IC is designed for portable electronic systems where internal USB high-speed ports may need to share a single USB connector. This IC is a bi-directional and allows sharing of a host USB port between multiple outputs such as in desktop or notebook PC, portable mini-printers or docking stations.

The ISL54222A can operate from a single 1.8V to 3.3V supply voltage. The ISL54222A offer Human Body Model (HBM) electrostatic discharge (ESD) performance of >12kV on input-output (I/O) terminals. Suitable applications for this include Smart Phones, MP3 players, personal navigation devices and digital cameras.

ISL54222A feature internal charge pumps to lower switch resistance and open the USB eye for better performance at 480 Mbps. It has two SPDT (Single Pole/Double Throw) switches configured as a DPDT.

With low switch leakage during power off conditions and with power-saving output-enable control to keep all switches open when no USB interface is in use, reduce power consumption to less than 1µA. Low on-Resistance and low-capacitance switches meet USB requirements while providing operating margins for noise and cable reflections. By tolerating over-voltages beyond the supply rails, the ISL54222A also meets USB 2.0 short-circuit requirements.

The 5.5-ohm switches can swing rail-to-rail and are designed to pass USB full-speed data signals that range from 0V to 3.6V and USB high-speed data signals that range from 0V to 400mV

Operating temperature range: -40 to +85 degrees C.
