The SC-70-6 package (also called SOT-363) takes minimal board area — useful when you're retrofitting an existing layout that has margin trouble on the I²C bus. ## Temperature grade and where it fits Rated for 0°C to 70°C commercial operation. That covers office equipment, consumer electronics, lab instruments, and indoor telecom gear. Not the part for an engine bay, outdoor base station, or cold-chain sensor pod — those need the industrial-temperature LTC4311ISC6#TRPBF variant, which extends to -40°C to 85°C. ## Sourcing this part — what to expect ROHS3 compliance means the part meets current environmental restrictions for lead and other hazardous substances, simplifying compliance for products sold into regulated markets.","metaTitle":"LTC4311CSC6#TRMPBF I²C Accelerator, 400kHz, SC-70-6","metaDescription":"Analog Devices LTC4311CSC6#TRMPBF single-channel I²C bus accelerator. 1.6V-5.5V supply, 200µA supply current, 400kHz data rate, SC-70-6.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Type":"Accelerator","Input":"2-Wire Bus","Output":"2-Wire Bus","Package":"Tape & Reel (TR); Cut Tape (CT)","Applications":"I²C","Mounting Type":"Surface Mount","Package / Case":"6-TSSOP, SC-88, SOT-363","Data Rate (Max)":"400kHz","lifecycle_stage":"eol_hot","Current - Supply":"200µA","Voltage - Supply":"1.6V ~ 5.5V","Number of Channels":"1","Operating Temperature":"0°C ~ 70°C","Supplier Device Package":"SC-70-6"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.03","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$5.03000","currency":"USD"},{"qty":10,"price":"$4.51900","currency":"USD"},{"qty":25,"price":"$4.27240","currency":"USD"},{"qty":100,"price":"$3.70270","currency":"USD"},{"qty":250,"price":"$3.51280","currency":"USD"},{"qty":500,"price":"$3.15200","currency":"USD"},{"qty":1000,"price":"$2.65832","currency":"USD"},{"qty":2500,"price":"$2.52540","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/6765523e036255fba8021eb9365b85a4.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can LTC4311CSC6#TRMPBF work with a 1.8V supply?","answer":"Yes. The supply range is 1.6V to 5.5V, so 1.8V logic buses are within spec. The part will accelerate rise times on a 1.8V I²C bus without needing a separate regulator."},{"question":"Is LTC4311CSC6#TRMPBF compatible with 5V I²C buses?","answer":"Yes. The 1.6V to 5.5V supply range covers 5V logic. The part's output is 2-wire bus, same as its input, so it passes 5V-level signals correctly."},{"question":"What is the LTC4311CSC6#TRMPBF used for?","answer":"It is an I²C bus accelerator that sharpens rising edges on SDA and SCL lines, allowing the bus to drive higher capacitive loads — longer PCB traces, more slave devices, or connectors — while maintaining 400kHz data rate."},{"question":"When sourcing LTC4311CSC6#TRMPBF, what is the closest functional alternate?","answer":"The LTC4311CDC#TRMPBF is the same accelerator in a different package (SC-70-6 vs DFN). Same 400kHz data rate, same 1.6V supply minimum, same single-channel I²C acceleration. The LTC4311ISC6#TRPBF is the industrial-temperature (-40°C to 85°C) version in the same SC-70-6 package."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/LTC4311CSC6TRMPBF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/LTC4311CSC6TRMPBF when reusing this data.
