between two I2C buses whose grounds are isolated from
one another. Each LTC4310 encodes I2C bus logic states
into signals that are transmitted across an isolation barrier
to another LTC4310. The receiving LTC4310 decodes the
transmission and drives its l2C bus to the appropriate logic
state. The isolation barrier can be bridged by an inexpensive
Ethernet, or other transformer, to achieve communications …
