1. Characterized value, not tested in production.
2. With CL = 10 pF.
3. 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.
4. To avoid spurious Start and Stop conditions, a minimum delay is placed between SCL=1 and the falling or
rising edge of SDA.

6. WC=0 set up time condition to enable the execution of a WRITE command.
7. WC=0 hold time condition to enable the execution of a WRITE command.
