I²C Repeaters

Nexperia's I²C repeaters represent cutting-edge solutions for extending the reach and reliability of I²C bus systems in modern electronic designs. As the demand for more complex and distributed systems grows, maintaining signal integrity across longer distances becomes increasingly challenging. Our I²C repeaters effectively address these challenges by regenerating I²C signals, enabling robust communication across extended bus lengths while preserving the protocol's timing requirements. These devices are engineered to support both standard-mode (100 kHz) and fast-mode (400 kHz) I²C operations, with some variants capable of handling high-speed mode (3.4 MHz) applications. The repeaters feature bidirectional buffering capabilities, allowing them to isolate capacitance on different bus segments and prevent signal degradation. This isolation is particularly valuable in systems with multiple I²C devices, where cumulative capacitance can limit performance. Nexperia's I²C repeaters incorporate advanced features such as rise time accelerators, which actively pull up the bus during rising edges to improve signal quality and reduce overall system power consumption. Many of our repeaters also include voltage level translation functionality, enabling seamless communication between devices operating at different supply voltages—a critical capability in mixed-voltage systems commonly found in industrial automation, automotive electronics, and consumer applications. The devices are designed with system reliability in mind, featuring built-in protection against bus contention and support for hot-swap applications. Their compact packaging options, including industry-standard DFN and TSSOP packages, make them ideal for space-constrained designs. With low standby current consumption and wide operating voltage ranges, Nexperia's I²C repeaters deliver optimal performance across diverse application environments, from automotive infotainment systems and industrial control panels to medical equipment and IoT devices. Our comprehensive portfolio ensures designers can find the perfect repeater solution for their specific I²C extension requirements, backed by Nexperia's reputation for quality and reliability.
