Wideband Differential 3:1 Multiplexer

ISL54233

The Intersil ISL54233 is a single supply differential 3 to 1

multiplexer that operates from a single supply in the range of

2.7V to 4.6V. It was designed to multiplex between three

different differential data sources, allowing the multiplexing of

USB 2.0 high speed data signals, UART data signals and digital

video through a common headphone connector in Personal

Media Players and other portable battery powered devices.

The switch channels have low ON capacitance and high

bandwidth (1.6GHz) to pass USB high speed signals (480Mbps)

and digital video signals with minimal edge and phase distortion

and can swing rail-to-rail to pass UART and full-speed USB

signals.

All channels of the multiplexer can be turned OFF (disabled) by

driving the C0 and C1 logic pins to the low state.

The ISL54233 is available in a tiny 12 Ld 2.2mmx1.4mm

ultra-thin QFN and 12 Ld 3mmx3mm TQFN package. It operates

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