The TCA9509DGKR from Texas Instruments is a two-channel I2C buffer and repeater supplied in an 8-pin VSSOP package. It supports bus frequencies up to 400 kilohertz, operates from 900mV to 5.5V, and has a propagation delay of 132.8ns. The TCA9509DGKR measures 3mm by 3mm with a 1.07mm height and is rated from -40°C to 85°C.
An I2C bus is limited by total capacitance, so adding devices or extending the wiring eventually slows the rising edges until communication fails. A buffer and repeater splits the bus into segments and drives each one separately, restoring the edges and letting a design exceed the capacitance a single segment allows. Its wide 900mV to 5.5V range also lets the TCA9509DGKR bridge between bus segments running at different logic levels, such as a 1.8V processor talking to 3.3V or 5V peripherals. It is used on backplanes, server management buses, industrial controllers, and any board where I2C must reach across connectors or long traces.
