The ADG3249 is a 2.5V or 3.3V, 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. This allows the input to be connected to different voltage sources without any interference. The switch is available in a low power SOT-23 package.
The ADG3249 is a high-performance 2:1 multiplexer/demultiplexer bus switch designed on a low voltage CMOS process. It operates from 2.5 V or 3.3 V supplies and features selectable level shifting/translation to convert between 3.3 V, 2.5 V, and 1.8 V logic levels.
