I
trt(pu)
varies with temperature and V
CC
voltage, as shown in
Section 11.1 “Typical performance characteristics”
.
The connection circuitry always regulates its output to a higher voltage than its input. The magnitude of this offset voltage as a function
of the pull-up resistor and V
CC
voltage is shown in
Section 11.1 “Typical performance characteristics”
.
C
b
= total capacitance of one bus line in pF.

SCLIN
= 0.1 V, tie SDAOUT and SCLOUT through 10 k
resistor to V
CC
and measure the SDAOUT and SCLOUT
output.
