description
These devices consist of two independent voltage
comparators that are designed to operate from a
single power supply over a wide range of voltages.
Operation from dual supplies also is possible as
long as the difference between the two supplies is 2 V to 36 V, and VCC is at least 1.5 V more positive than the
input common-mode voltage. Current drain is independent of the supply voltage. The outputs can be connected
to other open-collector outputs to achieve wired-AND relationships.
The LM193 is characterized for operation from –55°C to 125°C. The LM293 and LM293A are characterized for
operation from –25°C to 85°C. The LM393 and LM393A are characterized for operation from 0°C to 70°C. The
LM2903 and LM2903Q are characterized for operation from –40°C to 125°C and are manufactured to
demanding automotive requirements.

implied. Exposure to absolute-maximum-rated conditions for extended periods may af fect device reliability.
NOTES: 1. All voltage values, except differential voltages, are with respect to the network ground.
2. Differential voltages are at IN+ with respect to IN–.

These devices consist of two independent voltage comparators that are designed to operate
from a single power supply over a wide range of voltages. Operation from dual supplies also
is possible as long as the difference between the two supplies is 2 V to 36 V, and VCC is at
least 1.5 V more positive than the input common-mode voltage. Current drain is
independent of the supply voltage. The outputs can be connected to other open-collector
outputs to achieve wired-AND relationships.
The LM193 is characterized for operation from -55°C to 125°C. The LM293 and LM293A
are characterized for operation from -25°C to 85°C. The LM393 and LM393A are
characterized for operation from 0°C to 70°
C. The LM2903 and LM2903Q are characterized
for operation from -40°C to 125°C and are manufactured to demanding automotive
requirements.
