Its output stage supports DTL, MOS, open-collector, open-emitter, RTL, and TTL logic families, making it a versatile interface between analog threshold circuits and digital logic inputs. The 0.25µA maximum input bias current at ±15V and 7.5mV maximum input offset voltage suit precision threshold detection in low-frequency signal chains. The wide single-supply range (5V to 36V) lets it share a rail with 5V logic or 24V industrial sensors without a separate regulator, simplifying the power tree. Quiescent current is 7.5mA maximum, a reasonable budget for a general-purpose comparator in a mixed-signal design.","metaTitle":"LM311M/NOPB General Purpose Comparator, 0°C–70°C, 8-SOIC","metaDescription":"Texas Instruments LM311M/NOPB general-purpose comparator in 8-SOIC.
