描述/排序信息these devices consist of two independent voltagecomparators that are designed to operate from asingle power supply over a wide range of voltages.operation from dual supplies also is possible aslong as the difference between the two supplies is2 V to 36 V，and VCC至少比輸入共模電壓多1.5V.電流漏independent of the supply voltage.the outputs can be connected to other open-collector outputs to achievewired-and relationships.the LM193 is characterized for operation from−55°C to 125°C.the LM293 and LM293A are characterized foroperation from−25°C to 85°C.the LM393 and LM393A are characterized for operation from 0°C to 70°C.theLM2903 is characterized for operation from−40°C to 125°C.
