Note 1: All parameters tested at a single temperature. Specifications over temperature are guaranteed by design.
Note 2: Timing specifications guaranteed by design.
Note 3: The serial interface resets when SMBCLK is low for more than t
.
Note 4: A transition must internally provide at least a hold time to bridge the undefined region (300ns max) of
SMBCLK
s falling edge.
