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.
