Product Description

The TI P82B715TD Bus Extender is an I2C Signal Booster designed to enhance communication robustness in multidrop or long-distance I2C bus applications. This device features dual bidirectional channels, enabling it to extend I2C bus lines by amplifying current and voltage levels, supporting up to 32 connected modules per bus segment. It operates across a wide voltage range of 2.5V to 15V and can function in temperatures from -40°C to +85°C, making it suitable for industrial automation, automotive systems, and embedded control environments. The P82B715TD excels in mitigating signal degradation over extended cables while maintaining compatibility with standard I2C protocols. Its primary advantage lies in simplifying system design for distributed I2C networks, though it requires careful termination for optimal performance. This extender does not integrate power management or display components, focusing solely on signal integrity enhancement.
