As an alternative to consider, Analog Devices makes a
nifty little chip
that's got 422 and 232 drivers and receivers on it, and is +5
powered--AD7306.

Looks interesting. I wonder if you can get 1-offs anywhere (I've not
looks yet). On the other hand, the 26LS3x's and the MAX232 are easy to
obtain (even though they take up more board area).
