Maximum Current Input for 555

I was looking over a datasheet for the NE555 Timer (here is the datesheet of ne555n)and I was wondering if the max supply current given under the electrical characteristics page is the max current you can supply to the 555 without damaging the chip.

I ask because it seems like the supply current (for 15V input) is relatively low (10mA) compared to the output current (225mA).

Is the supply current the max current you can put on pin 8 without burning out the chip? If so, why is it so low compared to the output current? If not, how does one find the input current?
