The LM339-MIL device consists of four independent precision voltage comparators with an offset voltage specification as low as 2 mV maximum for all four comparators. These comparators were 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 is independent of the magnitude of the power supply voltage. These comparators also have a unique characteristic in that the input common-mode voltage range includes ground, even though they are operated from a single power supply voltage. The LM339-MIL device was designed to directly interface with TTL and CMOS. When operated from both plus and minus power supplies, the device directly interfaces with MOS logic where the low-power drain of the LM339-MIL is a distinct advantage over standard comparators.
