HS 2-Input Exclusive-OR Gate
General Description
The NC7S86 is a single 2-Input high performance CMOS
Exclusive-OR Gate. Advanced Silicon Gate CMOS fabrica-
tion 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. Inputs are well buffered from the output to
assure high noise immunity and reduced sensitivity to input
edge rate.

Absolute Maximum Ratings
(Note 1)
Recommended Operating
Conditions
(Note 2)
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.

AC Electrical Characteristics
Note 3: 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:
I
