SMBus DIGITAL SWITCHING CHARACTERISTICS
Unless otherwise noted, these specifications apply for V
CC
=+3.0 Vdc to +3.6 Vdc, C
(load capacitance) on output lines = 80
pF.
Boldface limits apply for T

to T
;
= T
= +25C, unless otherwise noted.
The switching characteristics of the LM84 fully meet or exceed the published specifications of the SMBus or I
2
C bus. The fol-
lowing parameters are the timing relationships between SMBCLK and SMBData signals related to the LM84. They are not nec-
essarily the I
2
C or SMBus bus specifications.
