Product Overview

The LTC4317CDHC#PBF is a dual I²C/SMBus Address Translator enables the hardwired address of one or more I²C or SMBus slave device 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 LTC4317 incorporates a pass-through mode which disables the address translation and allows general call addressing by the master. It is designed to automatically recover from abnormal bus conditions like bus stuck low or premature STOP bits. It has two output channels for two different sets of slaves. It bridges two segments of an I²C bus, reading incoming addresses on the master side and retransmitting them to the slave side with the 7-bit I²C addresses translated in real time.
  • Allows multiple slaves with the same address to coexist on the same bus
  • Resistor configurable address translation
  • No software programming required
  • Pass-through mode allows general call addressing
  • Stuck bus timeout
  • Prevents SDA and SCL corruption during live board insertion and removal from backplane
  • Support bus hot swap
