Part Number: TXB0108


We are using a TXB0108 translator to translate 1V2 xczu3eg FPGA bank push-pull logic to 3V3 push-pull logic on MT9V032 sensor. If we use the TXB, it damages the FPGA irrecoverably on first turn on. During turn on the FPGA is High-Z.

If a TXS0108 translator is used, this behavior is not observed.

The board in question is Ultra96-V2

What could be causing the issue?
