DESCRIPTION

The TS3V3702 is a micropower dual CMOS volt- age comparator with extremely low consumption of 7µA 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 timesremain similar to the LM393.

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 V CC can cause excessive heating and eventual destruction.
