Monolithic, Quad SPST, CMOS Analog
Switches
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.
These switches feature lower analog ON resistance (<85Ω)
and faster switch time (t
ON
<250ns) compared to the DG211
and DG212. Charge injection has been reduced, simplifying
sample and hold applications.
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.
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.
