DESCRIPTION
These devices consist of four independent preci-
sion voltage comparators, designed to operate
with single or dual supplies.
These differential comparators use the STMicro-
electronics silicon lin MOS process giving them an
excellent consumption-speed ratio.
These devices are ideally suited for low consump-
tion applications.
