TXS0108E: TXS0108E Input and Output Waveform Problem

Part Number:TXS0108E

Hi team,

I have a question of TXS0108E. Here is the test system.

We found that there will be a slow rising edge for the first pulse, but the second one didn't have. The waveform is like this. The blue one is the D0 on the CPU side and the yellow one is the D0 on the FLASH side. They both have a slow rising edge.

The rising edge is like this

And we found that this will occur on the both input and output side.

But when they removed the TXS0108E. There will be no problem.

Do you have any suggestion about this?

Thank you

Best Regards

Jack Chen
