General Description
The NC7SZ57 and the NC7SZ58 are Universal Configurable 2-Input Logic Gates. Each device is capable of
being configured for 1 of 5 unique 2-input log ic functions.
Any possible 2-input combinatorial logic function can be
implemented as shown in the Function Selection Table.
Device functionality is selected by how the device is wired
at the board level. Figure 1 through Figure 10 illustrate how
to connect the NC7SZ57 and NC7SZ58 respectively for the
desired logic functi on. All inputs have been impl emented
with hysteresis.
The device is fabricate d with advanced CMOS technology
to achieve ultra high speed with high output drive while
maintaining low stati c power dissip ation over a b road V
operating range. Th e device is specified to operate ov er
the 1.65V to 5.5V V

voltages up to 5.5V independent of V
operating range. The inp ut and ou t-

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.
