HS 2-Input NOR Gate
General Description
The NC7S02 is a single 2-Input high performance CMOS
NOR Gate. Advanced Silicon Gate CMOS fabrication
assures high speed and low power circuit operation over a
broad V
CC
range. ESD protection diodes inherently guard
both inputs and output with respect to the V
CC
and GND
rails. Three stages of gain between inputs and outputs
assures high noise immunity and reduced sensitivity to
input edge rate.

Note 1:
Absolute maximum ratings are those values beyond which damage
to the device may occur. The databook specifications should be met, with-
out exception, to ensure that the system design is reliable over its power
supply, temperature, and output/input loading variables. Fairchild does not
recommend operation of circuits outside databook specifications.
Note 2:
Unused inputs must be held HIGH or LOW. They may not float.

C
PD
is defined as the value of the internal equivalent capacitance which is derived from dynamic operating current consumption (I
CCD
) at no output
loading and operating at 50% duty cycle. (See Figure 2.) C
PD
is related to I
CCD
dynamic operating current by the expression:
