nn 20-Lead QFN 4mm × 4mm Package The LTC®4318 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. nn The LTC4318 incorporates a pass-through mode which
disables the address translations and allows general call
addressing by the master. The LTC4318 is designed to …
