Note 2:  If both the local and the remote junction are below T
A
= -20癈, then V
CC
> 3.15V.
Note 3: For conversion rates of 4Hz or slower, the conversion time doubles.
Note 4: Timing specifications guaranteed by design.
Note 5: The serial interface resets when SMBCLK is low for more than t
TIMEOUT
.
Note 6: A transition must internally provide at least a hold time to bridge the undefined region (300ns max) of SMBCLK's falling edge.
