DESCRIPTION
The TS393 is a micropower CMOS dual voltage
comparator with extremely low consumption of
9
m
A 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. 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.
