PIC sinking voltages higher that Vdd???

[skimask]

You're right, it does say that. But it also says that PORTA.4 has protection diodes to VDD and VSS.

Which one are we supposed to believe?

I suppose a little testing would tell.

YES! DESTRUCTIVE TESTING! I LOVE IT!
I've pulled 9v at about 5mA thru A.4 before, don't know if it was determental to the chip or not, but it seemed to work while I was doing it and I am still using the chip.

On the same note, I'm in Tucson, Az. for another couple of weeks. Man is it dry down here! I'm getting some killer static shocks from the doorknob! zzzztttt

so nobody else use 2 i/o to double the voltage around those cuties?

EDIT : Aw crap... we talked about piezo buzzer right... not sounder... sorry

unless you want to heard something different than it's suppose to be... forget it
