(Thin shrink small outline package) Description
The 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 opencollector output comparators. Pin connections
