Q100 qualification data available on request. 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.

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.
