The LT3960 is a robust high speed transceiver that extends a single-master I²C bus through harsh or noisy environments at up to 400kbps using the CAN-physical layer. One LT3960 sits near the I²C master, creating from SCL and SDA equivalent differential buses (I²CAN) on two twisted pairs. At the other end of the twisted pairs, a second LT3960 recreates the I²C bus locally for any slave I²C devices. A built-in 3.3V LDO powers both the I²C and I²CAN buses from a single input supply from 4V to 60V. Alternatively, the LT3960 can be powered directly from a 3.3V or 5V supply.

The LT3960 is available in a 10-lead MSOP package.
