        Well it depends on what you are doing. The lower limit is governed by the
max current that can go into a pin. Since you are going the other way we
won't worry about that limit. The upper limit depends on your application.
If for example you're connecting your output to the gate of a transistor the
upper limit is determined by the parasitic current flowing into the gate and
the Vthreshold of the transistor (assuming static operation, if you want
quick dynamic operation the limit is much lower). Since the current going
into a gate is so tiny this limit is probably in the realm of hundreds of
mega ohms, at least. To find out what is your limit we need to know what you
are connecting the output to. TTYL
