DESCRIPTION
The TS3702 is a micropowerCMOS dual voltage
comparator with extremely low consumption of
9µA typ / comparator (20 times less than bipolar
LM393). The push-pull CMOSoutput stage allows
powerandspacesavingbyeliminatingthe external
pull-up resistor required by usual open-collector
output comparators.
Thusresponse times remain similar to the LM393.

2. Differential voltages are the non-inverting input terminal with respect tothe inverting input terminal.
3. The magnitude of the input and the output voltagesmust never exceed themagnitude of the positive supply voltage.
4. Short circuit from outputs to V
