We use TXB0304 to transfer 33MHz and 16MHz CLK from 1V8 to 3V3.

The topology list show as below:

Topology 1: QSPI 16MHz trace length is 14" after level-shift, the waveform of CLK can't be recognized.

 Is there any solution…

Hi,

I encounter a issue about current, the schematic is as follows,

Story:

Step 1.  When the voltage of VDD_EXT changes from 1.8V to 0V, the current of TXBN0304 will be as high as 400uA(20pcs out of 100pcs chips will have this issue…

Dear,

I use TXB0106 for SPI level shift from 1.8V to 1.2V.When clock data rate is 20M,out waveform is incorrect 

The out waveforms are as follow.
