Description
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.
