Skew for the level translator 74AVC32T245EC?

We are using the voltage level translator 74AVC32T245EC for 1.8V to 3.3V level translation (A -> B). There are 4x 8-bit bus namely 1An, 1Bn, 1Cn and 1Dn. And also I understand that the propagation delay provided (For ex:) is 0.5ns (min) to 3.3ns (max) for the case of Vcc(A) = 1.8V, Vcc(B) = 3.3V.


The bus frequency is 150 MHz (max) and to analyze the timings, we need to know the maximum possible skew for signals as below:


1. Within a bus (1A1 to 1A2 or 2A1 to 2A7)

2. Across a bus (1An to 2An or 3An or 4An)


I was not able to locate this information in the 74AVC32T245EC datasheet and hence your quick support would be helpful.
