https://community.nxp.com/t5/Digital-Signal-Controllers/NVT2002-application-issue/m-p/1332745#M2236 <P>Hello NXP team:</P><P><SPAN>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&nbsp;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!</SPAN></P> Wed, 01 Sep 2021 00:32:16 GMT PhenixYu 2021-09-01T00:32:16Z https://community.nxp.com/t5/Digital-Signal-Controllers/NVT2002-application-issue/m-p/1332745#M2236 <P>Hello NXP team:</P><P><SPAN>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&nbsp;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?
