ADV7611 and ADV7513 voltage translation

In the datasheets of 7611 and 7513, it is mentioned that HPD, DDC_SCL, DDC_SDA and CEC pins are 3.3V input, which are 5V tolerant. I see that in the EVMs of 7611 and 7513, no voltage translation from 3.3V to 5V is done. They are directly pulled to 5V supply. (and a ESD protection is provided). Can you please confirm if it is safe to use it without voltage translation circuit and using them as 5V inputs/outputs. Also, can you please also specify the maximum voltage that it can withstand (i.e. above 5V) so that i can cross-check with the power supply tolerance?
