Logic Configurations NC7SZ57

Figure 1 through Figure 5 show the logical functions that can be implemented using the NC7SZ57. The diagrams show the

DeMorgan’s equivalent logic duals for a given 2-input function. Next to the logical implementation is the board level physical

implementation of how the pins of the function should be connected.
