OPERATION
The LTC4316 is an I2C/SMBus address translator. It bridges The translated addresses are configured with external two segments of an I2C bus, reading incoming addresses resistors, and no extra software is required. An ENABLE on the master side and retransmitting them to the slave pin allows bus segments to be enabled and disabled, and side with the 7-bit I2C addresses translated in real time. the LTC4316 allows hot swapping isolated bus segments This allows multiple I2C devices with the same address together. to be connected to the same bus without interference. 4316fa 6 For more information www.linear.com/LTC4316
