GENERAL DESCRIPTION
The ADG3248 is a 2.5 V or 3.3 V, high performance 2:1
multiplexer/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. The low on
resistance 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
directions when on. The ADG3248 exhibits break-before-make
switching action, preventing momentary shorting when
switching channels.
The ADG3248 is available in a tiny 6-lead SC70 package.
