4. There is no min. or max. values for the input signal rise and fall times. It is however
recommended by the I²C specification that the input signal rise and fall times be more than 20
ns and less than 300 ns when fC < 400 kHz.

the falling or rising edge of SDA.

6. tCLQV is the time (from the falling edge of SCL) required by the SDA bus line to reach either
0.3VCC or 0.7VCC, assuming that Rbus × Cbus time constant is within the values specified in
Figure 10.
