Hello - I'm designing a small serial data based controller system and have
been considering the use of a PIC as it appears that the ports can be used
to power other peripherals as they can sink/source some 20mA (can't do that
with the old standby 8051 variants I'm used to).

My question is this - what is the voltage level on a port pin that is set
to "high" and is sourcing near it's  maximum current?  The data sheets in
the microchip databook only show a Vdd-0.7 for a source current of -3mA.  I
will be sourcing at least 10 mA and perhaps 15.

Thanks for any assistance people can provide.
