Without it, plugging a card into an active bus glitches the clock and data lines, potentially locking up the entire I2C segment. This part isolates the card's bus capacitance from the backplane and actively accelerates rising edges through a pull-up current boost, keeping the bus within the 400 kHz data rate limit even with multiple cards connected. ## 8-MSOP package — rework-friendly with care The 8-MSOP package (3.00 mm width) is small enough for dense layouts but still hand-solderable with a fine-tip iron or hot-air station. The 10 pF input capacitance per channel is low enough that it won't load the bus noticeably; the buffer's job is to hide the card's own capacitance from the backplane.","metaTitle":"LTC4307CMS8#TRPBF I2C Hot-Swap Buffer, Accelerator, 400 kHz","metaDescription":"LTC4307CMS8#TRPBF I2C bus buffer/accelerator for hot-swap cards. 2-channel, 2.3V–5.5V supply, 400 kHz data rate, 8-MSOP package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Type":"Buffer, Accelerator","Input":"2-Wire Bus","Output":"2-Wire Bus","Package":"Tape & Reel (TR); Cut Tape (CT)","Applications":"I2C - Hotswap","Mounting Type":"Surface Mount","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width)","Data Rate (Max)":"400kHz","lifecycle_stage":"eol_hot","Current - Supply":"8mA","Voltage - Supply":"2.3V ~ 5.5V","Number of Channels":"2","Capacitance - Input":"10 pF","Operating Temperature":"0°C ~ 70°C","Supplier Device Package":"8-MSOP"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.25","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.25000","currency":"USD"},{"qty":10,"price":"$5.64600","currency":"USD"},{"qty":25,"price":"$5.38320","currency":"USD"},{"qty":100,"price":"$4.67430","currency":"USD"},{"qty":250,"price":"$4.46420","currency":"USD"},{"qty":500,"price":"$4.07030","currency":"USD"},{"qty":1000,"price":"$3.54510","currency":"USD"},{"qty":2500,"price":"$3.41380","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/468eaaa897345e4940d6be3190243d6d.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/LTC4307CMS8TRPBF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/LTC4307CMS8TRPBF when reusing this data.
