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 V
CC
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.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect 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–.
3. Short circuits from outputs to VCC can cause excessive heating and eventual destruction.
4. The package thermal impedance is calculated in accordance with JESD 51.
