GENERAL DESCRIPTION
The ADG3248 is a 2.5 V or 3.3 V, high performance 2:1 multi-
plexer/demultiplexer. 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 bounce noise.
Each switch of the ADG3248 conducts equally well in both direc-
tions when on. The ADG3248 exhibits break-before-make
switching action, preventing momentary shorting when switch-
ing channels.
The ADG3248 is available in a tiny 6-lead SC70 package.
PRODUCT HIGHLIGHTS
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 SC70 package.
