Cb = capacitance of one bus line in pF
The maximum t_of for the I²C data and clock bus lines quoted in the AC table is longer than the specified
maximum t_of for the output stages (250nS). This allows series protection resistors (R_S) to be connected between
I²C data / clock pins and the I²C data / clock bus lines without exceeding the maximum specified t_of.
The I²C bus operation voltage is 1.8V, The ALS-PDIC17-57B supply voltage mustÙ3V (3Vx0.6=1.8V)
