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.
