IL
specification is for the first LOW level seen by the SDAn/SCLn lines. V
ILc
is for the second and subsequent LOW levels seen by the
SDAn/SCLn lines.
[2] The SCLn/SDAn C
i
is about 200 pF when V
CC
= 0 V. The PCA9515A should be used in applications where power is secured to the
repeater but an active bus remains on either set of SCLn/SDAn pins.
