Description
The TSX3704 is a micropower CMOS quad
voltage comparator which exhibits a very low
current consumption of 5 µA typical per
comparator. This device was designed as the
improvement of the TS3704: it shows a lower
current consumption, a better input offset voltage,
and an enhanced ESD tolerance. The TSX3704
is fully specified over a wide temperature range
and is proposed in automotive grade for the
TSSOP14 package. It is fully compatible with the
TS3704 CMOS comparator and is available with
similar packages. The new tiny package, QFN16
3x3, is also proposed for the TSX3704 thus
allowing even more integration on applications.
Features
Low supply current: 5 µA typ. per
comparator
Wide single supply range 2.7 V to 16 V or
dual supplies (±1.35 V to ±8 V)
Extremely low input bias current: 1 pA typ.
Input common-mode voltage range includes
ground
Push-pull output
12
High input impedance: 10 Ω typ
Fast response time: 2.7 µs typ. for 5 mV
overdrive
ESD tolerance: 4 kV HBM, 200 V MM

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+).
