MAX 9000 Programmable Logic Device Family Data Sheet  
Parallel Expanders  
Parallel expanders are unused product terms that can be allocated to a  
neighboring macrocell to implement fast, complex logic functions.  
Parallel expanders allow up to 20 product terms to directly feed the  
macrocell ORlogic, with five product terms provided by the macrocell and  
15 parallel expanders provided by neighboring macrocells in the LAB.  
Figure 5 shows how parallel expanders can feed the neighboring  
macrocell.
