Its output stage can be configured as MOS, open-collector, open-emitter, or TTL, which lets the comparator drive logic inputs, relay coils, or optocouplers directly, depending on the pull-up or pull-down scheme chosen. Quiescent current is 7.5 mA max, which is moderate for a comparator running from a 30 V rail; the thermal budget in the 8-SOIC package is adequate for indoor use but not for high-density boards with limited airflow.","metaTitle":"Texas Instruments LM311DRG4 Comparator","metaDescription":"General-purpose comparator from TI.
