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.
