Pass-Through Mode Allows General Call Addressing
±4kV HBM ESD Ruggedness

Level Translation for 2.5V, 3.3V and 5V Buses
Stuck Bus Timeout
Prevents SDA and SCL Corruption During Live Board Insertion and Removal
Support Bus Hot Swap^™
10-Lead MSOP and DFN 3mm × 3mm Packages

The LTC4316 enables the hardwired address of one or more I²C or SMBus slave devices to be translated to a different address. This allows slaves with the same hardwired address to coexist on the same bus. Only discrete resistors are needed to select the new address and no software programming is required. Up to 127 different address translations are available.

The LTC4316 incorporates a pass-through mode which disables the address translation and allows general call addressing by the master. The LTC4316 is designed to automatically recover from abnormal bus conditions like bus stuck low or premature STOP bits.
