DESCRIPTION
The TS3V3702 is a micropower dual CMOS voltagecomparator withextremelylow consumption of
7µA typ / comparator (20 times less than bipolar
LM393). Thepush-pull CMOS output stage allows
powerandspacesaving byeliminatingtheexternal
pull-up resistor required by usual open-collector
output comparators.
Thus responsetimesremain similarto theLM393.

2. Differential voltages are the non-inverting input terminal with respect to the invertinginput terminal.
3. The magnitude of theinput and the output voltages must never exceed the magnitudeof the positive supply voltage.
4. Short circuit from outputs toV
