It sits between a master and a slave or on a long bus segment, actively pulling the SDA and SCL lines high during the rising edge to sharpen edges and reduce rise time. This lets the bus run at its rated 400 kHz data rate even with higher capacitive loading — think longer traces, multiple connectors, or a few extra devices on the same pair of wires. ## 400 kHz — the Fast-mode ceiling This part is rated for 400 kHz maximum, the I²C Fast-mode limit. The 60 µA supply current means it can sit on an always-powered bus segment without draining the rail. ## Active production — no LTB clock ticking ROHS3 compliant.","metaTitle":"LTC1694IS5#TRPBF I²C Bus Accelerator, 400 kHz, TSOT-23-5","metaDescription":"LTC1694IS5#TRPBF I²C bus accelerator from Analog Devices. 400 kHz data rate, 60 µA supply, -40°C to 85°C, TSOT-23-5.
