Webb9 apr. 2016 · The TI range extender adds a buffered bus that can connect local and i2c busses. On each end, you can still make use of the 400pF capacitance limit for i2c devices. The long cable is on a "buffered bus" with a load limit of 3000pF. For CAT5 cabling, that equates to about 60m length between the local and remote i2c devices.

I can get them in a number of configurations, and packages, set the I/O port differently, etc.. And they all pretty much use the same software. Plus, if I want, I can add other I2C peripherals without using up pins and using pretty much the same software.
