LM339 Description The LM339 consists of four independent voltage comparators. These 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 curr ent drain is independent of the magnitude of the power supply voltage. The outputs can be connected to other open - collector outputs to achieve wired -AND relationships. Features § § § § § § § § § Wide supply voltage range Low supply current drain independent of supply voltage. Low input biasing current Low input offset current Low input offset voltage Input common-mode voltage range includes GND Differential input voltage range equal to the power supply voltage Low output saturation voltage Output voltage compatible with TTL, MOS and CMOS logic 14 1 DIP - 14 www.DataSheet4U.com 14 1 SOP – 14 Package Internal Block Digram PIN CONNECTIONS symbol (each comparator) Output 2 Output 1 VCC – Input 1 + Input 1 – Input 2 + Input 2 1 2 3 4 5 6 7 14 13 12 Output 3 Output 4 Gnd + Input 4 – Input 4 + Input 3 – Input 3 IN+ OUT IN– *1 ) *2 ) (Top View) 4 ) * ) * 11 10 9 8 3 BEIJING ESTEK ELECTRONICS CO.,LTD 1 LM339 Absolute Maximum Ratings Symol Parameter Power Supply Voltages Value UNIT V CC V IDR V I CR tS Single Supply Split Supplies Input Differential Voltage Range Input Common Mode Voltage Range (1) 36 ±18 36 -0.3 to VCC 100 50 150 -65 to +150 260 1.0 8.0 V V V ms mA Short-Circuit duration of Output Input Current, per pin (2) Junction Temperature Plastic www.DataSheet4U.com Tstg TL PD * T Package °C °C °C W m W/ °C Storage Temperature Lead Temperature, 1mm from Case for 10 Seconds Power Dissipation T A=+25 °C Plastic Package Derate Above 25 °C Maximum Ratings are those Vvalues beyond which damage to the device may occur.

All characteristics are measured with zero common - mode input voltage unless otherwise specified. * The voltage at either input or common - mode should not be allowed to go negative by more than 0.3 V. The upper end of the common - mode voltage range is VCC - 1.5 V, but either or both inputs can go to 30 V without damage.
