ST TS3702 handbook
Datasheet
TS3702 is a micropower CMOS dual voltage comparator with extremely low consumption of 9μA typ / comparator (20 times less than bipolar LM393). The push-pull CMOS output stage allows power and space saving by eliminating the external pull-up resistor required by usual open- collector output comparators. Thus response times remain similar to the LM393.
