LTC4317IDHC#PBF

LTC4317 is a dual I²C/SMBus address translator. It enables the hardwired address of one or more I²C or SMBus device to be translated to a different address. This allows device 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. Upto 127 different address translations are available. It incorporates a pass-through mode which disables the address translation and allows general call addressing by the host. It is designed to automatically recover from abnormal bus conditions like bus stuck low or premature STOP bits. It is widely used in applications such as I²C, SMBus address expansion, address translation, servers, telecom etc.
