Bus enabler products and technologies

As its inventor, we understand the I²C-bus better than anyone else. The I²C format provides designers with a simple, low-cost way to meet tight deadlines while delivering the right level of performance. To ensure you have the best solutions for your next-generation designs, NXP continues to develop products using new technologies.

Our technologies – standard mode, Fast-mode, Fast-mode Plus, high-speed mode – are the ‘enablers’ of I²C. They bring the I²C-bus ‘to life’, with an extensive range of products that deliver, extend or manage I²C-bus functionality. They include bridges, buffers, controllers, level translators and muxes / switches in each of the technologies, making it easy for you to match a solution to your application requirements.
