Allows Multiple Slaves with the Same Address to
The LTC®4316 enables the hardwired address of one or
Coexist on the Same Bus
more I2C 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 n Compatible with SMBus, I2C and I2C 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
