Improved Low-Power,
CMOS Analog S witc hes with Latc hes
_______________General Desc ription
Maxim’s redesigned DG421/DG423/DG425 monolithic
analog switches now feature guaranteed on-resistance
matching (3
max) between switches and on-resistance
flatness over the signal range (4
max). These low on-
resistance switches (20
typ) conduct equally well in both
directions. They guarantee a low charge injection of 15pC
maximum and an ESD tolerance of 2000V minimum per
Method 3015.7. Off leakage current over temperature has
also been reduced (less than 5nA at +85°C).
The DG421/DG423/DG425 are precision, dual CMOS
switches with latchable logic inputs that simplify inter-
facing with microprocessors (μPs). The single-pole/single-
throw DG421 and double-pole/single-throw DG425 are
normally open dual switches. The dual, single-
pole/double-throw DG423 has two normally open and
two normally closed switches. Fast switching times
(175ns for t
ON
and 145ns for t
OFF
) and low power
consumption (35μW max) make these parts ideal for
battery-powered applications requiring μP-compatible
switches. Operation is from a single +10V to +30V supply,
or bipolar ±4.5V to ±20V supplies. Fabricated with the
same 44V silicon-gate process, these switches have
rail-to-rail signal handling capabilities.
