The LM339-MIL device consists of four independent precision voltage comparators with anoffset voltage specification as low as 2 mV maximum for all four comparators. These comparatorswere designed specifically to operate from a single power supply over a wide range of voltages.Operation from split power supplies is also possible and the low-power supply current drain isindependent of the magnitude of the power supply voltage. These comparators also have a uniquecharacteristic in that the input common-mode voltage range includes ground, even though they areoperated from a single power supply voltage.
The LM339-MIL device was designed to directly interface with TTL and CMOS. When operatedfrom both plus and minus power supplies, the device directly interfaces with MOS logic where thelow-power drain of the LM339-MIL is a distinct advantage over standard comparators.
