nn 16-Lead DFN 5mm × 3mm Package The LTC®4317 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. nn Applications
nn 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. …
