The single-element layout means you get one comparator in a five-pin SOT-23 footprint, useful when you need exactly one threshold detector on a dense board and a dual or quad package would waste space. ## Open-collector output — pull-up resistor and logic translation The output is open collector, so it sinks current only. A pull-up resistor to the logic supply rail is required. The output can sink up to 20mA typical. ## Package and footprint — SOT-23-5 for dense boards The TLV1391IDBVT ships in the SOT-753 package, with a supplier device package of SOT-23-5. That is a five-pin SOT-23 footprint. For BOM freeze purposes, this part can be designed in without worrying about a near-term EOL notice.","metaTitle":"TI TLV1391IDBVT Single Differential Comparator, SOT-23-5","metaDescription":"Texas Instruments TLV1391IDBVT single differential comparator with open-collector output, 2V–7V supply, 175µA quiescent, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Type":"Differential","Package":"Tape & Reel (TR); Cut Tape (CT)","Output Type":"Open Collector","Mounting Type":"Surface Mount","Package / Case":"SC-74A, SOT-753","lifecycle_stage":"eol_hot","Number of Elements":"1","Operating Temperature":"-40°C ~ 85°C","Current - Output (Typ)":"20mA","Supplier Device Package":"SOT-23-5","Current - Quiescent (Max)":"175µA","Current - Input Bias (Max)":"0.25µA @ 5V","Voltage - Input Offset (Max)":"5mV @ 5V","Voltage - Supply, Single/Dual (±)":"2V ~ 7V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.14","priceTiers":[{"qty":1,"price":"$1.14000","currency":"USD"},{"qty":10,"price":"$1.01900","currency":"USD"},{"qty":25,"price":"$0.96760","currency":"USD"},{"qty":100,"price":"$0.79480","currency":"USD"},{"qty":250,"price":"$0.74296","currency":"USD"},{"qty":500,"price":"$0.65656","currency":"USD"},{"qty":1250,"price":"$0.51834","currency":"USD"},{"qty":2500,"price":"$0.48900","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/d9d76507c9f09e48fc9604d8719bd990.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TLV1391IDBVT/alternatives.json"},"ai":{"faq":[{"question":"Is TLV1391IDBVT RoHS compliant?","answer":"Yes, TLV1391IDBVT is ROHS3 compliant, meeting the current EU RoHS directive without exemptions."},{"question":"What is the TLV1391IDBVT comparator used for?","answer":"The TLV1391IDBVT is a single differential comparator with an open-collector output. Typical applications include threshold detection (e.g., over-voltage or under-voltage monitoring), zero-crossing detection, level translation between different logic families, and window comparators for sensor signal conditioning in industrial and telecom environments."},{"question":"Is TLV1391IDBVT equivalent to LM393?","answer":"No, the TLV1391IDBVT is not a direct equivalent to the LM393. The LM393 is a dual comparator in an 8-pin package, while the TLV1391IDBVT is a single comparator in a 5-pin SOT-23-5. Both have open-collector outputs and similar supply ranges, but the pinout and package are different. For a single comparator in a small footprint, the TLV1391IDBVT is the closer fit."},{"question":"What is the difference between TLV1391 and LM393?","answer":"The primary differences are package and channel count. TLV1391IDBVT is a single comparator in a SOT-23-5 (5-pin) package. The LM393 is a dual comparator in an SOIC-8 or DIP-8 package. Both use open-collector outputs and operate from a 2V to 7V supply range. The TLV1391IDBVT draws a maximum quiescent current of 175µA per comparator, while the LM393 typically draws around 400µA per package (200µA per comparator)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TLV1391IDBVT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TLV1391IDBVT when reusing this data.
