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
