That is a neat part, too bad that it is no longer in production. Looks like Components Direct sells them individually.

I'm not sure that I would start a new design for manufacture with them, though.

If half-duplex will work, the DS275 might do. It's an 8-pin chip that steals power from the TxD of whatever you're plugged into to provide the negative swing for your TxD.
