The open-drain option lets you wire-AND multiple comparators on a single pull-up resistor — useful for window comparators or over-temperature detection chains. The 20 mA typical output current drives small relays or optocouplers directly. For motor drives or outdoor telecom enclosures, the industrial-grade LM393 variant (-40°C to 85°C) is the better fit.","metaTitle":"Texas Instruments LM393DRE4 Dual Differential Comparator","metaDescription":"TI LM393DRE4 dual differential comparator in 8-SOIC.
