The output stage supports CMOS, MOS, open-drain, and TTL logic families, giving the designer flexibility to interface with microcontrollers, PLDs, or discrete logic without a level translator. The open-drain output allows wired-OR configurations for shared interrupt lines or bus arbitration. It is not specified for industrial or automotive environments — if the board sees a motor drive enclosure or an engine bay, step up to the LM393 industrial-grade variant. ## SOIC-8 footprint — tape and reel for production The supplier device package is 8-SO.","metaTitle":"TI LM393APSR Dual Differential Comparator, 2V-36V, SOIC-8","metaDescription":"Texas Instruments LM393APSR dual differential comparator.
