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.
