“该器件有两个独立的电压比较器,可以单电源操作(在很宽的电压范围)。也可以双电源操作,但必须两个电源之间的差为2 V至36 V,VCC至少比输入共模电压大1.5 V。耗用电流与电源电压无关。输出可以连接到其他的集电极开路输出,以实现AND线连接。
”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.
