DEMO MANUAL DC2217A LTC4316 2 Single I C/SMBus Address Translator Description n Demonstration circuit 2217A features the LTC 4316 single Support for Bus Hot Swap 2 I C/SMBus address translator. The LTC4316 enables one n 10-Lead MSOP or DFN 3mm 3mm Package 2 or more I C or SMBus slave devices to translate their The LTC4316 incorporates a pass-through mode which hardwired address to a different address. This allows disables the address translating and allows general call slaves with the same address to coexist on the same addressing by the master. The LTC4316 is designed to bus. Only discrete resistors are needed to select the new automatically recover from abnormal bus conditions like address and no software programming is required. Up to bus stuck low or premature stop bits. There are three LTC 127 different translations are available. parts in this family with different numbers of inputs and The LTC4316 has a rich set of features including: outputs. The part numbers are as follows: n Allowing Multiple Slaves with the Same Address to PART NUMBER NUMBER OF INPUT NUMBER OF OUTPUT Coexist on the Same Bus.
