Hi Expert，
My customer is using SN74AXC8T245QPWRQ1 in their project. When they do the Propagation Delay timing test，VCCA=1.8V，VCCB=3.3V，the delay between B6→A6（UART_TX）is more than 4n.
In actual the sourcing and end equipment requirements has been meet. However, the value is more than our requirement on datasheet.
Would you mind helping me to identify if the delay could be accepted or not on IC level？Is there any risk?
Thanks a lot for your warm help!
Kind Regards
Imelda
