Boldface limits apply for TA =TJ =TMIN to TMAX; all other limits T A =TJ = +25˚C, unless otherwise noted. The switching characteristics of the LM89 fully meet or exceed the published specifi- cations of the SMBus version 2.0. The following parameters are the timing relationships between SMBCLK and SMBData sig- nals related to the LM89. They adhere to but are not necessarily the SMBus bus specifications.
