LTC4317IDHC#PBF

The LTC4317IDHC#PBF is a dual I?C/SMBus Address Translator enables the hardwired address of one or more I?C or SMBus slave device 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 LTC4317 incorporates a pass-through mode which disables the address translation and allows general call addressing by the master. It is designed to automatically recover from abnormal bus conditions like bus stuck low or premature STOP bits. It has two output channels for two different sets of slaves. It bridges two segments of an I?C bus, reading incoming addresses on the master side and retransmitting them to the slave side with the 7-bit I?C addresses translated in real time.
