Overview
LTC4316 Single I2C/SMBus Address Translator FEATURES n Allows Multiple Slaves with the Same Address to Coexist on the Same Bus n Resistor Configurable Address Translation n No Software Programming Required n Compatible with SMBus, I2C and I2C Fast Mode n Pass-Through Mode Allows General Call Addressing n ±4kV HBM ESD Ruggedness n Level Translation for 2.
5V, 3.
3V and 5V Buses n Stuck Bus Timeout n Prevents SDA and SCL Corruption During Live Board Insertion and Removal n Support Bus Hot Swap n 10-Lead MSOP and DFN 3mm × 3mm Packages APPLICATIONS n I2C, SMBus Address Expansion n Address Translation n Servers n Telecom 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.
