3 Description

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 lowpower

drain of the LM339-MIL is a distinct advantage

over standard comparators.
