DG444, DG445

Monolithic, Quad SPST, CMOS Analog Switches

FN3586

Rev 10.00

Jun 4, 2007

The DG444 and DG445 monolithic CMOS analog switches

are drop-in replacements for the popular DG211 and DG212

series devices. They include four independent single pole

single throw (SPST) analog switches and TTL and CMOS

compatible digital inputs.

and faster switch time (t

<250ns) compared to the DG211

and DG212. Charge injection has been reduced, simplifying

sample and hold applications.

• Low Charge Injection

• Upgrade from DG211, DG212

• TTL, CMOS Compatible

The improvements in the DG444 series are made possible

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

layer prevents the latch-up associated with older CMOS

technologies. The 44V maximum voltage range permits

controlling 20V signals when operating with 20V power

supplies.

• Single or Split Supply Operation

• Pb-Free Plus Anneal Available (RoHS Compliant)

Applications

The four 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.

The switches in the DG444 and DG445 are identical,

differing only in the polarity of the selection logic.

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.
