GENERAL DESCRIPTION  
PRODUCT HIGHLIGHTS  
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.  
1. 3.3 V or 2.5 V supply operation.  
2. Extremely low propagation delay through switch.  
3. 4.5 Ω switches connect inputs to outputs.  
4. Tiny SOT-23 package.  
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, VCC is  
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.
