See if the Allegro still makes the UCN-5818. (With various suffixes). Sprague Semi.(now Allegro) said that it was a replacment for the SN75518.

thanks Mark,
perfect suggestion if that chip were not as difficult to buy as the SN75518N. All those chips exist out there when i do search for them the SN75518N,UCN5818N,UCN6818 etc i just can not purchase them as they are stocked by huge chip warehouses and they only deal through brokers and the brokers only deal with minimum orders of $300-500
so i try to find solutions i can buy thanks again for your help, robb

Random suggestions: Jameco, JDR Microdevices, B&D Enterprises, (The mail/web order specialty distributors that are small order friendly and stock some surplus/chip pulls/older inventory). There's also places like Rochester Electronics who specialize in the discontinued parts but often deal with only mil-spec stuff ($$$$).
Your Milage may vary, I have not spent the time to see if they have any.
Also check out the thread "Obselete Devices" in Sci.electronics.design. one of the regulars has set up some sort of custom Google search that weeds out those parts brokers with imaginary inventory.
