Typical figures are at T A = 25°C and represent most likely parametric norms at the time of product characterization. The typical
specifications are not ensured.
Limits are specified to Texas Instruments' AOQL (Average Outgoing Quality Level).
Logic Electrical Characteristics SMBus Digital Switching Characteristics
Unless otherwise noted, these specifications apply for V DD =+3.0 Vdc to +3.6 Vdc, C L (load capacitance) on output lines = 80
pF. Boldface limits apply for T A = T J = T MIN to T MAX ; all other limits T A = T J = +25°C, unless otherwise noted.
The switching characteristics of the LM95241 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 LM95241. They
adhere to but are not necessarily the SMBus bus specifications.

Typical figures are at T A = 25°C and represent most likely parametric norms at the time of product characterization. The typical
specifications are not ensured.
Limits are specified to Texas Instruments' AOQL (Average Outgoing Quality Level).
The output rise time is measured from (V IN(0) max + 0.15V) to (V IN(1) min ? 0.15V).
The output fall time is measured from (V IN(1) min - 0.15V) to (V IN(1) min + 0.15V).
Holding the SMBDAT and/or SMBCLK lines Low for a time interval greater than t TIMEOUT will reset the LM95241's SMBus state machine,
therefore setting SMBDAT and SMBCLK pins to a high impedance state.
