    Can you post a link to a datasheet for the 555? Just look on the simplified schematic in the datasheet for the chip to see if you can find any inversion possibilities. BTW, is this a homework problem?

    Good, then it's posted in the right forum. Take a look at this datasheet (found it quickly with Google):

    http://cache.national.com/ds/LM/LM555.pdf

    Look at the simplified schematic of the 555 internal circuit, and then look at the typical waveforms farther down in the Applications section. Do you see how some waveforms go high when others go low, and visa-versa? Ther's your clue to how to make an inversion function....
