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