SMBus DIGITAL SWITCHING CHARACTERISTICS
Unless otherwise noted, these specifications apply for V
pF. Boldface limits apply for T
The switching characteristics of the LM84 fully meet or exceed the published specifications of the SMBus or I
lowing parameters are the timing relationships between SMBCLK and SMBData signals related to the LM84. They are not nec-
