Description
The TSX339 is a micropower CMOS dual voltage
comparator which exhibits a very low current
consumption of 5 µA typical per comparator. This
device was designed as the improvement of the
TS339: it shows a lower current consumption, a
better input offset voltage, and an enhanced ESD
tolerance. The TSX339 is fully specified over a
wide temperature range and is proposed in
automotive grade for the TSSOP14 package. It is
fully compatible with TS339 CMOS comparator
and is available with similar packages. The new
tiny package, QFN16 3x3, is also proposed for
the TSX339 thus allowing even more integration
on applications.

Notes:
(1)All voltage values, except the 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)Guaranteed by design
(4)Short-circuits can cause excessive heating and destructive dissipation. Values are typical

Notes:
(1)The output state is guaranteed as long as one input remains with this common-mode input voltage range, and
the other input remains between -0.3 V and 16 V (meaning that one input can be driven above VCC+).
