Slow rise/fall input time to SN74LVC8T245PW

Hi, 

We are using SN74LVC8T245PW to buffer 30MHz display signals. According to the SN74LVC8T245PW datasheet, the rise/fall time is 10ns/V when the VCC is 3.3V.

However I have measured that the signals input to the SN74LVC8T245PW on our product have a rise/fall time around 14ns(measured from Vilmax to Vihmin). The rise/fall transition is pretty monotonous w/o ringing. So I'd like to know what is the potential risk to have this slower rise/fall time? Will this damage the chip in long term, or just power consumption concern?

Thanks,

Peng
