ADG3249 - Analog Devices

ADG3249 2:1 Multiplexer/Demultiplexer Bus Switch

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. This allows the input to be connected to the output without additional propagation delay or generating additional ground bounc.
