It sits in a 12-MSOP package (0.118\", 3.00mm width) and operates from a 2.9 V to 5.5 V supply, drawing 8.1 mA typical. Rated for a maximum data rate of 400 kHz, it meets the standard I2C Fast-mode ceiling. The 10 pF input capacitance keeps bus loading predictable when multiple devices share the same 2-wire bus. The operating temperature range spans -40°C to 85°C, covering industrial enclosures and outdoor telecom cabinets without a grade upcharge. ## Supply range and current budget for the BOM The 2.9 V to 5.5 V supply range means this buffer works on both 3.3 V and 5 V I2C rails. The 8.1 mA supply current is the total draw from the VCC pin — budget this into the rail's total load, not just the I2C pull-up current. Because it is a hot-swap buffer, it isolates the bus capacitance of a plug-in card from the main bus. The 10 pF input capacitance is the load the buffer presents to the upstream bus, not the downstream side. ## Lifecycle and compliance posture The LTC4315IMS#TRPBF carries an active lifecycle status from Analog Devices. It is also ROHS3 compliant, so it meets the current EU restriction threshold without an exemption. Sourced through independent distribution channels; availability and current pricing are confirmed at RFQ against the BOM quantity.","metaTitle":"LTC4315IMS#TRPBF I2C Hot Swap Buffer, 400kHz, 12-MSOP","metaDescription":"Analog Devices LTC4315IMS#TRPBF I2C hot-swap buffer/accelerator, 2.9-5.5V supply, 8.1mA supply current, 400kHz max data rate, -40 to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"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":"12-TSSOP (0.118\\\", 3.00mm Width)","Data Rate (Max)":"400kHz","lifecycle_stage":"eol_hot","Current - Supply":"8.1mA","Voltage - Supply":"2.9V ~ 5.5V","Number of Channels":"1","Capacitance - Input":"10 pF","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"12-MSOP"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.32","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$8.32000","currency":"USD"},{"qty":10,"price":"$7.51300","currency":"USD"},{"qty":25,"price":"$7.16400","currency":"USD"},{"qty":100,"price":"$6.22040","currency":"USD"},{"qty":250,"price":"$5.94080","currency":"USD"},{"qty":500,"price":"$5.41664","currency":"USD"},{"qty":1000,"price":"$4.71771","currency":"USD"},{"qty":2500,"price":"$4.54298","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/9c867c34a9e7f1fbca913462ff3af423.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How can I order LTC4315IMS#TRPBF or check availability?","answer":"The LTC4315IMS#TRPBF is active and available to order through independent distribution.
