DESCRIPTION

The TS3V3704is a micropowerquadCMOSvolt­age comparatorwith extremelylow consumption
of 7µAtyp / comparator(20timeslessthanbipolar
LM339). The push-pull CMOSoutputstage allows
powerandspacesavingbyeliminatingtheexternal
pull-up resistor required by usual open-collector
output comparators.

Thus response times remain similarto the LM339.
