Product Overview
The LM339N is a Texas Instruments quad differential comparator in the Signal_Chain category. It integrates 4 independent voltage comparators and is specified for non-B LM339 family operation from a 2 to 30 V supply range, with 1 to 2.5 mA total supply current under the listed family comparison conditions.
Electrical limits include ±15 mV maximum input offset voltage over temperature, a listed secondary ±4 mV maximum input offset value, 25 nA typical and 250 nA maximum input bias current, and 1.3 µs typical response time. The common-mode input voltage range includes ground, and the output stage is compatible with TTL, MOS, and CMOS logic interfaces.
The LM339N package is a 14-pin PDIP (N), 19.30 mm x 6.40 mm. Pin assignments include VCC on pin 3 and GND on pin 12, outputs on pins 1, 2, 13, and 14, and comparator inputs on pins 4 through 11. Thermal data for the N package includes 114.9 °C/W junction-to-ambient resistance and 93.8 °C/W junction-to-case-top resistance.
