DESCRIPTION
The 82B715 is a bipolar integrated circuit intended for application in
I
While retaining all the operating modes and features of the I
system it permits extension of the practical separation distance
between components on the I
(SDA) and the clock (SCL) lines.
The I
communication distances to a few meters. Using one 82B715 at
each end of longer cables reduces the cable loading capacitance on
the I
cost general purpose wiring to extend bus lengths.
