The LTC4317 enables the hardwired address of one or more I2C 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. The LTC4317 is designed to automatically recover from abnormal bus conditions like bus stuck low or premature STOP bits.The LTC4317 has two output channels for two different sets of slaves. The input channels are tied together to a common set of pins to reduce the pin count and package size.Part NumberNumber of Input ChannelsNumber of Output ChannelsLTC431611LTC431712LTC431822ApplicationsI2C, SMBus Address ExpansionAddress TranslationServersTelecom
