Typical Application
Description
The LTC®4316 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.
The LTC4316 incorporates a pass-through mode which disables the address translation and allows general call addressing by the master. The LTC4316 is designed to automatically recover from abnormal bus conditions like bus stuck low or premature STOP bits.
