According to this datasheet (http://www.futurlec.com/74LS/74LS154.shtml) the 74ls154 is supposed to run on 5v (+ .25 volts), but I tried running it off of 2 AAA batteries and it worked. How is this possible?

It's guaranteed to work between 4.75V and 5.25V.  However, any given part will likely work well beyond that range, but I would not bet a consumer, commercial or medical product design on it as some will and some won't.

Speed would be the prime issue... Not as Fast.
