P82B715 I2C-bus extender Rev.
08 — 9 November 2009 Product data sheet 1.
General description The P82B715 is a bipolar IC intended for application in I2C-bus and derivative bus systems.
While retaining all the operating modes and features of the I2C-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 I2C-bus capacitance limit of 400 pF restricts practical communication distances to a few meters.
Using one P82B715 at each end of a long cable (connecting Lx/Ly to Lx/Ly) reduces that cable’s loading on the linked I2C-buses by a factor of 10 and allows the total system capacitance load (a...
