Description

The 82B715 is a bipolar integrated circuit intended for application in I² C bus systems.

While retaining all the operating modes and features of the I² C system it permits extension of the practical separation distance between components on the I² C bus by buffering both the data (SDA) and the clock (SCL) lines.

The I² C bus capacitance limit of 400pF restricts practical communication distances to a few meters. Using one 82B715 at each end of longer cables reduces the cable loading capacitance on the I² C bus by a factor of 10 times and may allow the use of low cost general purpose wiring to extend bus lengths.
