Are you sure you're reading the spec for the RS-232 side of the chip and not the TTL side?

Come on, Andy, it's a well known fact, that most RS-232 trancievers are designed to provide recievers that respond to TTL level inputs as well as EIA/TIA-232E and V.28 levels!

Have a look at page 14 of this datasheet:

You didn't know that??
