DG401, DG403
Monolithic CMOS Analog Switches
The DG401 and DG403 monolithic CMOS analog switches
have TTL and CMOS compatible digital inputs.
These switches feature low analog ON resistance (<45)
and fast switch time (tON<150ns). Low charge injection
simplifies sample and hold applications.
The improvements in the DG401, DG403 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 30VP-P signals. Power supplies may be
single-ended from +5V to +34V, or split from 5V to 17V.
The analog 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 three
different devices provide the equivalent of two SPST (DG401)
or two SPDT (DG403) relay switch contacts with CMOS or
TTL level activation. The pinout is similar, permitting a
standard layout to be used, choosing the switch function as
needed.

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.
