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

(<100Ω) and faster switch transition time (t

TRANS

< 250ns)

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.

NOTE: Intersil Pb-free products employ special Pb-free material

sets; molding compounds/die attach materials and 100% matte tin

plate termination finish, which is 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-020B.
