The TS3704 is a micropower CMOS quad voltage comparatorwith extremely low consumption of 9mAtyp / comparator (20 times less than bipolar LM339). The push-pull CMOS output stage allows power and spacesaving by eliminating the external pull-up resistor required by usual open-collector output comparators.
Thus response times remain similar to the LM339.

Notes : 1. All voltage values, except differential voltage, are with respect to network ground terminal. 2. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal. 3. The magnitude of the input and the output voltages must never exceed the magnitude of the positive supply voltage. 4. Short circuit from outputs to VCC + can cause excessive heating and eventual destruction.
