Steve, If you would like two footprints at two different locations on the pwb, you should show the device twice on the schematic with a note as to why. If you want one footprint that can except two different devices you can do that with a special footprint (named ssop14-ssop16??). The second option isn't uncommon with memory and RF devices. If you'd like two different devices because the breadboard uses a cheaper burn able device and your production uses a custom ASIC, or some such scenario, then I'd suggest two different schematics (or a revision to the same schematic). For this last option you can often buy or design a adapter daughter board to convert your cheap part to the production footprint. John
