Hello NXP team:

Recently, I used NVT2002DP to change the I2C signal level from 5V to 3.3V, details are that I2C master(NXP MCU 5V) on VerB, I2C device(3V3) on VerA according to reference design, but I have one issue, which is as below: when I2C master send the message to the device, I found that the VerB side waveform is normal, but on VerA side, the waveform is distorted , and the high level(3V3) cannot be down to low level(0V) normally(you can check the waveform), could you please help me resolve the issue? Thanks a lot!

Please use 1.74K resistors on B side for pull up to 5V.
