Grumpy_Mike:
You should not use capacitors on a raw pin output because at switch on a capacitor looks like a dead short and you will exceed the maximum current ratings in the pin.
You should not put capacitors on an output because it will do no good, not because you will exceed current ratings. Current ratings are for DC conditions. It is impossible to specify peak transient current.
When I was designing an output driver for a high capacitor load the designers of the next level of assembly became alarmed at the high peak currents being generated. They commissioned an analysis of the effects of the high peak currents. Conclusion: no problem.
