The is an I²C-bus Extender intended for application in IC-bus and derivative bus systems. While retaining all the operating modes and features of the IC-bus it permits extension of the practical separation distance between components on the I²C-bus by buffering both the data SDA and the clock SCL lines. The IC-bus capacitance limit of 400pF restricts practical communication distances to a few meters. Using this at each end of a long cable reduces that cables loading on the linked IC-buses by a factor of 10 and allows the total system capacitance load to be around 3000pF while the loading on each IC-bus on the Sx/Sy sides remains below 400pF. Longer cables, general-purpose wiring may be used to link IC-bus based modules without degrading noise margins.
