SMBus Digital Switching Characteristics

characteristics of the LM96163 fully meet or exceed the published specifications of the SMBus version 2.0. The following param-
eters are the timing relationships between SMBCLK and SMBDAT signals related to the LM96163. They adhere to but are not
necessarily the same as the SMBus bus specifications.
Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
functional, but do not guarantee performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed
specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test
conditions.
Note 2: All voltages are measured with respect to GND, unless otherwise noted.
Note 3: When the input voltage (V
components and/or ESD protection circuitry are shown below for the LM96163's pins. Care should be taken not to forward bias the parasitic diode, D2, present
on pins D+ and D−. Doing so by more than 50 mV may corrupt temperature measurements.
