Each comparator can sink up to 20 mA at the open-collector output, which also supports CMOS, MOS, or TTL logic levels depending on the pull-up rail. Supply flexibility is the headline here: single-supply operation from 2 V to 30 V, or split supplies from ±1 V to ±15 V. ## Supply range and input offset — what actually matters for the BOM The 0.25 µA max input bias current at 5 V keeps the error low when driving from high-impedance sources like a thermistor divider. Quiescent current maxes at 2.5 mA for all four comparators combined. That's about 0.6 mA per channel, which is reasonable for a general-purpose comparator in a non-battery-critical design.","metaTitle":"LM339ADE4 Quad Differential Comparator, 14-SOIC, Active","metaDescription":"Texas Instruments LM339ADE4 quad differential comparator. 4 elements, open-collector output, 2V to 30V supply. 14-SOIC package.
