What is the max data rate for
Hi Parviz,
Welcome to the E2E Forums.
Just to give you a couple quick tips before I get directly to your question:
The Logic Forum has a Frequently Asked Questions section that often helps out, located here:
Also, we have recently started releasing videos to help out with common applications of logic and translation devices, located here: 
Now, to get to the answer of your question. I'm afraid that in this particular case that I don't have a specific value to give you. The device isn't specified to a maximum frequency. We typically recommend this device for slower speed (under 100 MHz) signals. The AUP family is primarily targeted at low power applications rather than high speed.
If you're after something faster, the SN74AVC1T45 is recommended to 500 Mbps for 1.8V to 3.3V translation. We also have a number of other gates that could work for translation depending on the specific application.
