description/ordering information
NC No internal connection
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 affect 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. Maximum power dissipation is a function of TJ(max), JA, and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD = (TJ(max) TA)/JA. Operating at the absolute maximum TJ of 150°C can affect reliability. 5. The package thermal impedance is calculated in accordance with JESD 51-7. 6. Maximum power dissipation is a function of TJ(max), JC, and TC. The maximum allowable power dissipation at any allowable case temperature is PD = (TJ(max) TC)/JC. Operating at the absolute maximum TJ of 150°C can affect reliability. 7. The package thermal impedance is calculated in accordance with MIL-STD-883.
