ADG3249 - 2:1 Multiplexer/Demultiplexer Bus Switch

Description

The ADG3249 is a 2.5 V or 3.3 V, high performance 2:1 multiplexer/demultiplexer bus switch.

It is designed on a low voltage CMOS process, which provides low power dissipation yet gives high switching speed and very low on resistance.
