SERIAL BUS DIGITAL SWITCHING CHARACTERISTICS Unless otherwise noted, these specifications apply for +V
S=+2.7V
to +5.5V for LM92CIM . Boldface limits apply for T
A =TJ =TMIN to TMAX; all other limits TA=TJ=+25 ˚C, unless otherwise
noted. CL (load capacitance) on output lines = 80 pF unless otherwise specified. Boldface limits apply for T
A =TJ =TMIN to

MAX; all other limits TA =TJ = +25 ˚C, unless otherwise noted.
The switching characteristics of the LM92 fully meet or exceed the published specifications of the I
2C bus. The following pa-
rameters are the timing relationship between SCL and SDA signal related to the LM92. They are not the I
2C bus specifica-
tions.
