Rated for 400 kHz data rate, it supports standard I2C Fast-mode operation. The 3 mA supply current is the chip's own draw; the bus pull-up resistors add to the total load, but the buffer isolates that from the backplane side during insertion. The 10 pF input capacitance per channel is low enough that adding the buffer to an existing bus doesn't significantly load the upstream master's rise time budget. ## Package and temp grade — commercial MSOP for controlled environments Housed in an 8-MSOP package (3.00 mm body width), the LTC4300A-3CMS8#TRPBF is a surface-mount part suited for reflow assembly. The supplier device package is 8-MSOP. Shipped in Tape & Reel (TR) with Cut Tape (CT) option — the TR suffix on the order code signals reel packaging for automated pick-and-place. ## Active production and compliance — no end-of-life concern ROHS3 compliant per the lifecycle entry. The closest sibling in form and function is the tube-packaged LTC4300A-3CMS8#PBF — same die, same ratings, same pinout, just shipped in a tube instead of a reel. If your assembly line runs tubes, that variant is a direct drop-in.","metaTitle":"LTC4300A-3CMS8#TRPBF I2C Buffer Accelerator, 400kHz, 8-MSOP","metaDescription":"Analog Devices LTC4300A-3CMS8#TRPBF I2C hotswap buffer/accelerator. 400kHz data rate, 2.7-5.5V supply, 3mA supply current, 2 channels, 8-MSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"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":"3mA","Voltage - Supply":"2.7V ~ 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":"$6.26","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.26000","currency":"USD"},{"qty":10,"price":"$5.62500","currency":"USD"},{"qty":25,"price":"$5.31760","currency":"USD"},{"qty":100,"price":"$4.60860","currency":"USD"},{"qty":250,"price":"$4.37228","currency":"USD"},{"qty":500,"price":"$3.92324","currency":"USD"},{"qty":1000,"price":"$3.30876","currency":"USD"},{"qty":2500,"price":"$3.14332","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between LTC4300A-3CMS8#TRPBF and LTC4300A-3CMS8#PBF?","answer":"The only difference is the shipping format: the TRPBF variant comes on Tape & Reel for automated assembly; the PBF variant ships in a tube."},{"question":"What is the supply current of LTC4300A-3CMS8#TRPBF?","answer":"The device draws 3 mA typical supply current.
