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.

• Low Charge Injection
• Upgrade from DG211, DG212
• TTL, CMOS Compatible
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 44V, or split from ±5V to ±20V.
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 ±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 (#2 and #3) 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.
