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.
