Note 1: TA = +25°C to +85°C.
Note 2: If both the local and the remote junction are below TA = -20°C, then VCC > 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 tTIMEOUT.
Note 6: A transition must internally provide at least a hold time to bridge the undefined region (300ns max) of SMBCLK's falling edge.
