DG408, DG409

Single 8-Channel/Differential 4-Channel,

CMOS Analog Multiplexers

The DG408 Single 8-Channel, and DG409 Differential

4-Channel monolithic CMOS analog multiplexers are drop-in

replacements for the popular DG508A and DG509A series

devices. They each include an array of eight analog

switches, a TTL/CMOS compatible digital decode circuit for

channel selection, a voltage reference for logic thresholds

and an ENABLE input for device selection when several

multiplexers are present.

The DG408 and DG409 feature lower signal ON resistance

(<100

Ω) and faster switch transition time (t

compared to the DG508A or DG509A. Charge injection has

been reduced, simplifying sample and hold applications. The

improvements in the DG408 series are made possible by

using a high-voltage silicon-gate process. An epitaxial layer

prevents the latch-up associated with older CMOS

technologies. Power supplies may be single-ended from +5V

to +34V, or split from

±5V to ±20V.

The analog switches are bilateral, equally matched for AC or

bidirectional signals. The ON resistance variation with

analog signals is quite low over a

±5V analog input range.

*Add “-T” suffix for tape and reel.

**Pb-free PDIPs can be used for through hole wave solder processing only. They are not intended for use in Reflow solder processing applications.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte tin plate

termination finish, which are RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free products are MSL

classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
