Propagation delay is 1 µs typical — fast enough for overcurrent detection, zero-crossing, and window comparators in motor drives and power supplies, but not for high-speed data paths. The open-collector, CMOS, MOS, and TTL-compatible output lets it drive logic inputs or pull-up to a different voltage rail. ## Supply range and quiescent current Input bias current is 0.025 µA maximum at 5 V, so the comparator does not load high-impedance sensor outputs. Input offset voltage is 2.5 mV maximum at 36 V, adequate for threshold detection where the hysteresis is set externally. The output can sink 21 mA typical at 5 V, enough to drive an LED indicator or a small relay coil through a transistor.","metaTitle":"LM393BIDGKR Differential Comparator, 1µs, 2V-36V, 8-VSSOP","metaDescription":"Texas Instruments LM393BIDGKR dual differential comparator. 1µs typ propagation delay, 2V to 36V supply, open-collector/CMOS/MOS/TTL output.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Type":"Differential","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Hysteresis":"-","Output Type":"Open-Collector, CMOS, MOS, TTL","Mounting Type":"Surface Mount","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","CMRR, PSRR (Typ)":"-","Number of Elements":"2","Base Product Number":"LM393","Operating Temperature":"-40°C~85°C","Current - Output (Typ)":"21mA @ 5V","Propagation Delay (Max)":"1µs (Typ)","Supplier Device Package":"8-VSSOP","Current - Quiescent (Max)":"600µA","Current - Input Bias (Max)":"0.025µA @ 5V","Voltage - Input Offset (Max)":"2.5mV @ 36V","Voltage - Supply, Single/Dual (±)":"2V ~ 36V, ±1V ~ 18V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4700","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM393BIDGKR/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM393BIDGKR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM393BIDGKR when reusing this data.
