Hi, TI Support Team
My client is measuring timing for the TCA6408A-Q1.
I have a question about I2C Interface Timing described in the datasheet.
There is a Min. value for Ticf in Fast Mode.
Of course, Min. values exist for other values as well.
Is the Min. value written in Fast Mode a spec that must be observed?
The Min. value of Ticf is calculated to be about 6ns, but the timing seen through the oscilloscope seems to be ps.
Please check whether the Min. value is a part that must be observed.
Min. value exists even in standard mode, but what I am curious about is the part about Ticf.
Could you please check if the attached waveform is ok?
As you can see from the waveform, the falling edge drops sharply.
The timing at this time is difficult to measure, but it is expected to be ps.
