The NC7SZ57 and NC7SZ58 are universal configurable two-input logic gates. Each device is capable of being configured for 1 of 5 unique two-input logic functions. Any possible two-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. Figures 4 through 13 illustrate how to connect the NC7SZ57 and NC7SZ58, respectively, for the desired logic function. All inputs have been implemented with hysteresis.

The device is fabricated with advanced CMOS technology to achieve ultra high speed with high output drive while maintaining low static power dissipation over a broad V_CC operating range. The device is specified to operate over the 1.65V to 5.5V V_CC operating range. The input and output are high impedance when V_CC is 0V. Inputs tolerate voltages up to 5.5V independent of V_CC operating range.
