Ahhh...,  Sorry folks, I must have been brain dead when I wrote this.
The 7106/7107 pair is a A/D convertor with on chip lcd/led drivers. 
The chip needed to hook a 4 digit lcd to a microcontroller is the
7211/7212 series. They drive Non-multiplexed displays, like the 
fe203 lcd or reguler led 7-segment displays. On to answering the 
real question (16 digit display controllers).....

  Intersil also makes some chips to do the 8 and 16 wide displays. 
Some part numbers are: ICM7218  (controls 8 digits of muxed led),
or the ICM7243A, which controls 14-segment 8 wide displays. There is
also the ICM7233/7234 which controls 18-segment 4 wide displays.
I found these and other interesting specs in the intersil applications
handbook. The only phone number I could find on the book is this:

  GE Solid State
  408-996-5000

Hope this clears up any problems my first post caused (Gee, I better
not take any tests in that state of mind....)
