ELECTRICAL CHARACTERISTICS (continued)
(Circuit of Typical Operating Circuit, V
= 3.3V and T
Note 1: T
Note 2: If both the local and the remote junction are below T
Note 3: Conversions done in extended mode. For legacy mode, current is approximately half.
Note 4: Timing specifications guaranteed by design.
Note 5: The serial interface resets when SMBCLK or SMBDATA is low for more than t
Note 6: A transition must internally provide at least a hold time to bridge the undefined region (300ns max) of SMBCLK’s falling edge.
