Description
S
MiniSO8
(plastic package)
Pin-to-pin and functionally compatible with
the dual CMOS TS393 comparators
See the TSX3702 for push-pull output
The TSX393 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
TS393: it shows a lower current consumption, a
better input offset voltage, and an enhanced ESD
tolerance. The TSX393 is fully specified over a
wide temperature range and is proposed in
automotive grade for the SO8 package. It is fully
compatible with the TS393 CMOS comparator
and is available with similar packages. New tiny
packages (MiniSO8 and DFN8 2x2 mm) are also
proposed for the TSX393 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)Excursions
of input voltages may exceed the power supply level. As long as the common mode voltage (Vicm =
(Vin+) + (Vin-)/2) remains within the specified range, the comparator provides a stable output state. However, the
maximum current of the input stage, through the ESD diodes (IF), must be strictly observed.
(4)Guaranteed

(5)Short-circuits

can cause excessive heating and destructive dissipation. Values are typical.

TSX393
Application information (input voltages)
The ESD strategy used in the TSX393 (and shown in Figure 2 allows input voltages from 0.3 V up to 16 V to be applied regardless of the VCC+ voltage. When VIN > VCC+ a leakage
current goes from the input through the protection diode to the ESD clamp. This current is
about 0.2 nA at 25 °C and about 250 nA at 125 °C. For a detailed input characteristic see
Figure 12. The device is designed to prevent phase reversal.
