I would highly recommend using a bypass capacitor, 100nF ceramic is fine. Chances are is that it will work, to some degree, without it. Needless to say: without a bypass capacitor your device could work marginally, ie. it works one day and the next day it quits. If you value time/reliability more than components/space then the capacitor is a good idea. Datasheet suggest that the case is already connected to ground.
