DESCRIPTION
The TS393 is a micropower CMOS dual 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 TS3702 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. Excursions of input voltages may exceed the power supply level. As long as the common mode voltage [Vicm=(Vin+ + Vin- )/2]
remains within the specified range, the comparator will provide a stable output state. However, the maximum current through
the ESD diodes (If) of the input stage must strictly be observed. The output must never exceed the power supply voltage.
4. Guaranteed by design.
5. Short circuit from outputs to VCC+ can cause excessive heating and eventual destruction.
