DG408L/409L
Vishay Siliconix
Precision 8-Ch/Dual 4-Ch Low Voltage Analog Multiplexers
DESCRIPTION
The DG408L/409L are low voltage pin-for-pin compatible
companion devices to the industry standard DG408/409 with
improved performance.
Using BiCMOS wafer fabrication technology allows the
DG408L/409L 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 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/409L provides lower on-resistance, faster
switching time, lower leakage, less power consumption and
higher off-Isolation than the DG408/409.
