SMBus Digital Switching Characteristics
Unless otherwise noted, these specifications apply for V
Boldface limits apply for T
The switching characteristics of the LM95235 fully meet or exceed the published specifications of the SMBus version 2.0. The
following parameters are the timing relationships between SMBCLK and SMBDAT signals related to the LM95235. They adhere
to, but are not necessarily, the SMBus specifications.
SMBus Clock Frequency
SMBus Clock Low Time
SMBus Clock High Time
SMBus Rise Time
SMBus Fall Time
Output Fall Time
SMBDAT and SMBCLK Time Low for Reset of Serial
Interface (Note 14)
Data In Setup Time to SMBCLK High
Data Out Stable after SMBCLK Low
Start Condition SMBDAT Low to SMBCLK Low (Start
condition hold before the first clock falling edge)
Stop Condition SMBCLK High to SMBDAT Low (Stop
Condition Setup)
SMBus Repeated Start-Condition Setup Time,
SMBCLK High to SMBDAT Low
SMBus Free Time Between Stop and Start Conditions
