Well, Microchip says that "High current sink/source" of the
I/O pins are one of the benefits with the PICmicro line
compared with "other" micros. And the S/T inputs are there
to help read un-conditioned signals, not ?

Now, maybe that both "small loads" and "high current"
as well as "conditioned" needs to be specified more closly :-)
