Description
LTC4316
Single I

C/SMBus
Address Translator
Demonstration circuit 2217A features the
LTC
®
4316
single
I
2
C/SMBus address translator. The LTC4316 enables one
or more I
2
C or SMBus slave devices to translate their
hardwired address to a different address. This allows
slaves with the same 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 translations are available.
The LTC4316 has a rich set of features including:
n
Allowing Multiple Slaves with the Same Address to
Coexist on the Same Bus.

The LTC4316 incorporates a pass-through mode which
disables the address translating 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. There are three LTC
parts in this family with different numbers of inputs and
outputs. The part numbers are as follows:

DC2217A demonstrates only the LTC4316. The other parts
provide similar functions with differences listed in their
respective data sheets.
