High-Speed USB 2.0 (480Mbps) Multiplexer

ISL54222A

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.

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 1.8mmx1.4mm

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.
