Hi team,
Our customer is using TXS0108E, and they encountered a leakage problem.
According to the datasheet description, the I/O pin should be Hi-Z when OE=0V.
But the customer found that there is a leakage current on Pin14 when OE=0V. This will cause their system cannot be turned on.
Below is the FA report. The leakage current of suspect IC is 310uA, and that of a good die is only 130uA. (condition: Pin14=0.5V, VCCA=VCCB=OE=0V)
There are 6 ICs having this problem in 30 samples. Why the leakage current of suspect IC is much higher than normal one?? And the variation is very high.

Now the customers want to know the I/O leakage or impedance spec (MIN/MAX values) when OE=low, which is not specified in datasheet.
Would you please help to provide the data? Thank you.
