Help with flash chip datasheet, says maximum voltage on pins is 0.5V?

I saw it in one and then realized they all have it, this one Alliance Memory-AS29CF800T/B-55TIN says it very explicitly under the "notes" on page 6.

It's powered by 5V but its pins can only be 0.5V at max? That can't be true? I don't actually have to voltage divide or use a buffer of some sort for all 27 pins do I?

And then I just realized that right above there in the absolute maximum ratings it says the IO pins can handle -2.0 to 6.5V? So it should be fine using 5V for everything? Thank you.

Probably a misprint......
Then the next line says this..........
During voltage transitions, input or I/O pins may overshoot to VCC +1.5V for periods up to 20ns.

.5v is an impractical limit in this application. As such, I'm going to side with typonese
