A =TJ =TMIN to TMAX; all other limits TA =TJ = +25C, unless otherwise noted. The switch-
ing characteristics of the LM99 fully meet or exceed the published specifications of the SMBus version 2.0. The following pa-
rameters are the timing relationships between SMBCLK and SMBData signals related to the LM99. They adhere to but are not
necessarily the SMBus bus specifications.
