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 14 1 SOP – 14 Package Internal Block Digram PIN CONNECTIONS symbol (each comparator) Output 2 1 14 Output 3 Output 1 2 13 Output 4 VCC 3 12 Gnd IN+ – Input 1 4 11 + Input 4 IN– + Input 1 5 10 – Input 4 – Input 2 6 9 + Input 3 8 – Input 3 + Input 2 7 * ) * ) 1 4 2 3 ) * ) * OUT (Top View) BEIJING ESTEK ELECTRONICS CO.,LTD 1 LM339 Absolute Maximum Ratings Symol Parameter Value UNIT 36 ±18 V 36 V -0.3 to VCC V Short-Circuit duration of Output 100 ms Input Current, per pin (2) 50 mA 150 °C -65 to +150 °C °C Power Supply Voltages V CC Single Supply Split Supplies V IDR Input Differential Voltage Range V I CR Input Common Mode Voltage Range (1) tS T Tstg Junction Temperature Plastic Package Storage Temperature TL Lead Temperature, 1mm from Case for 10 Seconds 260 PD Power Dissipation T A=+25 °C Plastic Package Derate Above 25 °C 1.0 8.0 W m W/ °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.
