ELECTRICAL CHARACTERISTICS (continued)
(Circuit of Typical Operating Circuit, VCC = 3.0V to 5.5V, TA = -25°C to +125°C, unless otherwise specified. Typical values are at VCC
= 3.3V and TA = +25°C.)
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: 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 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.
