description/ordering information
This device consists 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 LM2903Q is tested from 40°C to 125°C and is manufactured to demanding automotive requirements. ORDERING INFORMATION

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. The package thermal impedance is calculated in accordance with JESD 51-7.

Full range (MIN or MAX) for LM2903Q is 40°C to 125°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.
