DESCRIPTION
The TS3704is a micropower CMOS quad voltage
comparatorwith extremely low consumption
of9µAtyp / comparator(20 timesless thanbipolar
LM339). The push-pull CMOSoutputstage allows
powerandspacesavingbyeliminatingtheexternal
pull-up resistor required by usual open-collector
output comparators.
Thus responsetimes remain similarto theLM339.

2. Differentialvoltages are the non-invertinginput terminal withrespect to the inverting input terminal.
3. The magnitude of the inputand the outputvoltages mustnever exceed the magnitude of the positive supply voltage.
