Is PB5 really not 5V tolerant?

The data sheet I have says it isn't, and yet it's not an ADC input as all the other non 5V tolerant pins seem to be. Of course I'll believe the datasheet if there's no positive information that it's wrong, but it seems suspicious enough (and datasheets have been known to be wrong!) that I thought I'd ask if anybody has better info.

Grrrr, the board software discarded my first response.
Short answer (because I'm not willing to recreate the previous long message): PB5 is buggy. It's bitten me twice. It's likely that this pin was intended to be 5V tolerant, but the same bugs that broke MOSI and TIM3 output also broke the protection structure.- Mark as New

Ah, I didn't know about that ability. Thanks for pointing it out.
