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 is characterized for operation from –40°C to 125°C. The LM2903Q is tested from –40°C to 125°C and
is 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 af fect device reliability.
NOTES: 1. All voltage values, except differential voltages, are with respect to GND.
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 51-7.

†Full range (MIN or MAX) for LM193 is –55°C to 125°C, for LM293 is 25°C to 85°C, and for LM393 is 0°C to 70°C. All characteristics are measured
with zero common-mode input voltage, unless otherwise specified.
‡The voltage at either input or common-mode should not be allowed to go negative by more than 0.3 V . The upper end of the common-mode voltage
range is VCC+ – 1.5 V, but either or both inputs can go to 30 V without damage.
