TinyLogic
ULP Universal Configurable
2-Input Logic Gates
General Description
The NC7SP57 and the NC7SP58 are Universal Config-
urable 2-Input Logic Gates from Fairchild’s Ultra Low
Power (ULP) Series of TinyLogic
. Ideal for applications
where battery life is critical, this product is designed for
ultra low power consumption within the V
CC
operating
range of 0.9V to 3.6V. Each device is capable of being con-
figured for 1 of 5 unique 2-input logic functions. Any possi-
ble 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 NC7SP57 and NC7SP58 respectively for
the desired logic function. All inputs have been imple-
mented with hysteresis.
The internal circuit is composed of a minimum of inverter
stages including the output buffer, to enable ultra low
dynamic power.
The NC7SP57 and NC7SP58, for lower drive require-
ments, are uniquely designed for optimized power and
speed, and are fabricated with an advanced CMOS tech-
nology to achieve best in class operation while maintaining
extremely low CMOS power dissipation.

Logic Configurations NC7SP57
Figure 1 through Figure 5 show the logical functions that can be implemented using the NC7SP57. 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.

Note 1:
Absolute Maximum Ratings: are those values beyond which the
safety of the device cannot be guaranteed. The device should not be oper-
ated at these limits. The parametric values defined in the Electrical Charac-
teristics tables are not guaranteed at the absolute maximum ratings. The
“Recommended Operating Conditions” table will define the conditions for
actual device operation.
