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.

ON/OFF(EN)
• Low Charge Injection
The DG408 and DG409 feature lower signal ON resistance
(<100) and faster switch transition time (t
< 250ns)
• Upgrade from DG508A/DG509A
• TTL, CMOS Compatible
TRANS
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.
• Single or Split Supply Operation
• Pb-Free Plus Anneal Available (RoHS Compliant)
Applications
• Data Acquisition Systems
• Audio Switching Systems
• Automatic Testers
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.
• Hi-Rel Systems
• Sample and Hold Circuits
• Communication Systems
• Analog Selector Switch

**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.
