DG408L, DG409L
Vishay Siliconix
Precision 8-Ch/Dual 4-Ch Low Voltage Analog Multiplexers
DESCRIPTION
The DG408L, DG409L are low voltage pin-for-pin compatible
companion devices to the industry standard DG408, DG409
with improved performance.
Using BiCMOS wafer fabrication technology allows the
DG408L, DG409L to operate on single and dual supplies.
Single supply voltage ranges from 3 V to 12 V while dual
supply operation is recommended with ± 3 V to ± 6 V.
The DG408L 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 DG409L 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.
The DG408L, DG409L provides lower on-resistance, faster
switching time, lower leakage, less power consumption and
higher off-Isolation than the DG408, DG409.
