Abstract The availability of powerful I2C-bus buffers that drive their I/Os on both sides to
a nominal ground or ‘zero offset’ logic level allows the removal of noise
introduced into one section of a very large bus system. That ‘regeneration’ of
clean I2C signals enables building very long I2C buses by combining together
