Non-invertingInput 1
Inverting Input 2
-
The TS3702 is a micropower CMOS dual voltage
comparator with extremely low consumption of
9µA typ / comparator (20 times less than bipolar
LM393). The push-pull CMOS output stage allows
power and space saving byeliminating the external
pull-up resistor required by usual open-collector
output comparators.

Thus response times remain similar to the LM393.

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.
