Low-Voltage, Single-Supply,
10Ω SPST CMOS Analog Switches
General Description
____________________________Features
ꢀ Available in SC70-5 Package
ꢀ 10Ω max On-Resistance
ꢀ 1.5Ω max On-Resistance Flatness
ꢀ Fast Switching
The MAX4594–MAX4597 single-pole/single-throw
(SPST) analog switches operate from a single +2.0V to
+5.5V supply. The MAX4594/MAX4596 switches are
normally open (NO), and the MAX4595/MAX4597 are
normally closed (NC). The MAX4596/MAX4597 pinouts
are optimized for the highest SC70 package off-isola-
tion available.
