GENERAL DESCRIPTION

The ADG3249 is a 2.5 V or 3.3 V, high performance 2:1 multi-

plexer/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 propaga-

tion delay or generating additional ground bounce noise.

Each switch of the ADG3249 conducts equally well in both direc-

tions when on. The ADG3249 exhibits break-before-make

switching action, preventing momentary shorting when switch-

ing channels.

This device is ideal for applications requiring level translation.

When operated from a 3.3 V supply, level translation from

3.3 V inputs to 2.5 V outputs is allowed. Similarly, if the device

is operated from 2.5 V supply and 2.5 V inputs are applied, the

device will translate the outputs to 1.8 V. In addition, a level

translating pin (SEL) is included. When SEL is low, V

reduced internally, allowing for level translating between 3.3 V

inputs and 1.8 V outputs.

The ADG3249 is available in a tiny 8-lead SOT-23 package.
