Hello together,
we have changed our level translator for i2c bus to the TXS0102.
With the new transloter we got the problem, if connect two level shifter parallel there are some peaks on the SDA Line.
These peaks are at the same time as the high level on the SCL line. With an unfavorable constellation, the SDA line goes to low and then the CLK and thus a new start condition on the bus results and a bit shift occurs.
Furthermore I have removed the additional PullUp resister, but we got also the same problem.
If we connect only one level shifter to the pcb we have no peaks on the bus and the communication is working.
Has there ever been such a problem before?
And do you have any idea how we can solve this problem?
Thank you so much!
Best regards
Simon
