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 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.
