DESCRIPTION

The TS3702 is a micropower CMOS dual voltage

comparator with extremely low consumption of

9

µA 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.
