Vishay Siliconix
Precision 8-Ch/Dual 4-Ch Low Voltage Analog Multiplexers
DESCRIPTION
The DG3408, DG3409 uses BiCMOS wafer fabrication
technology that allows the DG3408/3409 to operate on sin-
gle and dual supplies. Single supply voltage ranges from 3
to 12 V while dual supply operation is recommended with
± 3 to ± 6 V.
The DG3408 is an 8-channel single-ended analog
multiplexer designed to connect one of eight inputs to a
common output as determined by a 3-bit binary address
(A0, A1, A2). The DG3409 is a dual 4-channel differential
analog multiplexer designed to connect one of four
differential inputs to a common dual output as determined by
its 2-bit binary address (A0, A1). Break-before-make
switching action to protect against momentary crosstalk
between adjacent channels.
