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....)
