LTC4316 2 Single I C/SMBus Address Translator FEATURES DESCRIPTION n Allows Multiple Slaves with the Same Address to The LTC 4316 enables the hardwired address of one or 2 Coexist on the Same Bus more I C or SMBus slave devices to be translated to a n Resistor Configurable Address Translation different address. This allows slaves with the same hard- n No Software Programming Required wired address to coexist on the same bus. Only discrete 2 2 n Compatible with SMBus, I C and I C Fast Mode resistors are needed to select the new address and no n Pass-Through Mode Allows General Call Addressing software programming is required. Up to 127 different n 4kV HBM ESD Ruggedness address translations are available. n Level Translation for 2.5V, 3.3V and 5V Buses The LTC4316 incorporates a pass-through mode which n Stuck Bus Timeout disables the address translation and allows general call n Prevents SDA and SCL Corruption During Live Board addressing by the master. The LTC4316 is designed to Insertion and Removal automatically recover from abnormal bus conditions like n Support Bus Hot Swap bus stuck low or premature STOP bits. n 10-Lead MSOP and DFN 3mm 3mm Packages NUMBER OF INPUT NUMBER OF OUTPUT PART NUMBER CHANNELS CHANNELS APPLICATIONS LTC4316 1 1 2 n LTC4317 1 2 I C, SMBus Address Expansion n LTC4318 2 2 Address Translation n Servers L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear Technology Corporation.
