Data Sheet

File Number

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 (<85鈩?
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
鹵20V
signals when operating with
鹵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
鹵5V
analog input range.
The switches in the DG444 and DG445 are identical,
differing only in the polarity of the selection logic.
