ORDERING INFORMATION
Device LM339D LM339N Package SOP 14 DIP 14
DESCRIPTION
The LM339 consists of four independent precision voltage comparators, with an offset voltage specification as low as 20㎷ max for each comparator, which 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 series was designed to directly interface with TTL and CMOS. When operated from both plus and minus power supplies, the LM339 series will directly interface with MOS logic where their low power drain is a distinct advantage over standard comparators.

* Full range (MIN to MAX), for LM339 is 0℃ to 70℃. All characteristics are measured with zero common-mode ** The voltage at either input or common-mode should not be allowed to go negative by more than 0.3V. The upper end of the common-mode voltage range is V CC -1.5V, but either or both inputs can go to 30V without damage.
