Hi all,

On a related note, how much of an output current margin do you guys
(doing high volume runs) maintain on individual I/O pins and on the
Ports.  For example, the 16F872 data sheet's "Absolute Max. Ratings"
states 25mA per pin (source or sink); 200mA for Ports A & B combined,
and 200mA for Port C.  That's nearly a half an AMP!

I'd like to drive a dual 7-seg display directly from the PIC @15mA per
segment (15*7=105mA on PortB, 105mA on PortC).
That's about 50% of the Abs. Max. Rating...  Safe?
