DESCRIPTION
The TS3V393 is a micropower dual CMOS voltage
comparator with extremely low consumption of
9µA typ / comparator (20 times less than bipolar
LM393). Similar performances are offered by the
dual micropower comparator TS3V3702 with a
push-pull CMOS output.
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.
