DESCRIPTION

The

DG9408/9409

uses

BiCMOS

wafer

fabrication

technology that allows the DG9408/9409 to operate on single

and dual supplies. Single supply voltage ranges from 3- to

12-V while dual supply operation is recommended with

"3 to

"6 V.

The DG9408 is an 8-channel single-ended analog multiplexer

designed to connect one of eight inputs to a common output

DG9409 is a dual 4-channel differential analog multiplexer

designed to connect one of four differential inputs to a common

Break-before-make switching action to protect against

momentary crosstalk between adjacent channels.
