[5] I
trt(pu)
varies with temperature and V
CC
voltage, as shown in Section 11.1 “Typical performance characteristics”.
[6] Input pull-up voltage should not exceed power supply voltage in operating mode because the rise time accelerator will clamp the voltage
to the positive supply rail.
[7] 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”.

and measure the SDAOUT and SCLOUT
output.
