Over the years, engineers have been turning to I2C for a broader range of uses due to its simplicity and low manufacturing cost. Some of these applications stretch the practical limits of the I2C bus in terms of distance or number of attached devices.

Learn more about the ways bus buffers are commonly used to overcome these limitations to:

  • Extend the bus to cover a greater distance
  • Increase the number of attached devices (slave loads)
  • Reduce capacitive loading on the bus
  • Increase drive strength for faster bus speeds

Ask questions of the team that has been innovating the use of I2C-bus buffers for over 30 years.



Peter Stonard, Application Engineer, BL Interface Products: Bus Buffers & Thermal Sensors, NXP

Peter relocated to the USA to work on EMI Medical X-Ray Scanners after earning an electrical engineering degree from Westminster University (formerly Harrow College) in London, UK. This lead to Peter’s creation of an in-house engineering team to design and construct unique factory and lab test equipment at Clinton Electronics, a Midwest based CRT builder. Peter moved to N. California to work for The Grass Valley Group (a Tektronix Company) as a design engineer on broadcast video and audio systems, at a time when traditional analog solutions were replaced with Serial Digital Interface standards. Peter joined Elantec Semiconductor prior to their IPO, as the Western Region Field Application Engineer, providing customer support and new product definition for high speed Op Amps and MUX switches. More recently Peter has worked for Comlinear, National Semiconductor, and Vishay Intertechnology, in various technical marketing roles.
