The DG411 series monolithic CMOS analog switches are
drop-in replacements for the popular DG211 and DG212
series devices. They include four independent single pole
throw (SPST) analog switches, and TTL and CMOS
compatible digital inputs.

• Upgrade from DG211/DG212
• TTL, CMOS Compatible
• Single or Split Supply Operation
The improvements in the DG411 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

single-ended from +5V to +34V, or split from ±5V to ±20V.
The four switches are bilateral, equally matched for AC or
bidirectional signals. The ON resistance variation with
analog signals is quite low over a ±15V analog input range.
The switches in the DG411 and DG412 are identical,
differing only in the polarity of the selection logic. Two of the
switches in the DG413 (#1 and #4) use the logic of the
DG211 and DG411 (i.e., a logic “0” turns the switch ON) and
the other two switches use DG212 and DG412 positive logic.
This permits independent control of turn-on and turn-off
times for SPDT configurations, permitting “break-before-
make” or “make-before-break” operation with a minimum of
external logic.
