LM193/LM293/LM293A/LM393/LM393 pdf
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.
