Monolithic CMOS Analog Switches

The DG401, DG403 and DG405 monolithic CMOS analog
switches have TTL and CMOS compatible digital inputs.

These switches feature low analog ON resistance (<45Ω)
and fast switch time (t

< 150ns). Low charge injection

ON

simplifies sample and hold applications.
The improvements in the DG401/403/405 series are made

possible by using a high voltage silicon-gate process . An
epitaxial layer pre vents the latch-up associated with older
CMOS technologies. The 44V maximum voltage range
permits controlling 30V

signals. Po w er supplies may be

P-P

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
differentdevicesprovidetheequivalentoftwoSPST(DG401),
two SPDT (DG403) or two DPST (DG405) relay s witch
contacts with CMOS or TTL level activ ation. The pinout is
similar, permitting a standard layout to be used, choosing the
switch function as needed.
