Each comparator can swing its open-collector output to match CMOS, TTL, MOS, ECL, or DTL logic families — the output pull-up voltage is independent of the comparator supply, so level translation between a 5 V sensor and a 3.3 V controller is one resistor away. ## Supply rails and temperature — where this part lives comfortably Single-supply operation from 2 V to 36 V, or split supplies from ±1 V to ±18 V, covers most industrial and consumer rails without a secondary regulator. ## Open-collector output and input offset — the practical limits","metaTitle":"LM339AMX/NOPB Quad Comparator, 2V-36V, SOIC-14, Active","metaDescription":"Texas Instruments LM339AMX/NOPB general-purpose quad comparator. 2V to 36V supply, open-collector outputs, 0°C to 70°C.
