Product Summary
The LM139 and LM339 series consists of four independent precisionvoltage comparators with an off set voltage specification a slow as 2 mV max for all four comparators. These weredesigned 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 currentdrain is independent of the magnitude of the power supplyvoltage. These comparators also have a unique characteristic in that the input common-mode voltage range includesground, even though operated from a single power supply voltage.
Parametrics
The absolute maximum ratings of LM339M are (1)Supply Voltage, V:+36 VDC or ±18 VDC; (2)Differential Input Voltage (Note 8):36 VDC; (3)Input Voltage:-0.3 VDC to +36 VDC; (4)Input Current (VIN<-0.3 VDC),(Note 3):50 mA; (5)Output Short-Circuit to GND,(Note 2):Continuous; (6)Storage Temperature Range:-65°C to +150°C; (7)Lead Temperature(Soldering, 10 seconds):260°C
Features
The features of LM339M can be summarized as (1)Wide supply voltage range; (2)Very low supply current drain (0.8 mA) — independent of supply voltage; (3)Low input biasing current:25 nA; (4)Low input offset current:±5nA; (5)Offset voltage:±3mV; (6)Input common-mode voltage range includes GND; (7)Differential input voltage range equal to the power supply voltage; (8)Low output saturation voltage:250 mV at 4 mA; (9)Output voltage compatible with TTL, DTL, ECL, MOSand CMOS logic systems
