Josh,
Yes, I'm pretty sure you can connect Vee and Vss together & connect to
0V. The only requirement is that the input signal does not go more
negative than 0V (or more positive than Vdd.

If you want to run the AC signal without a midrail bias, then Vee
needs to be pulled below 0V, Vss is the logic ground at 0V and Vdd is
the positive supply. Just  make sure that the other limits are not
exceeded.

Figure 9 gives a diagram of allowable configurations.
