TinyLogic
UHS 2-Input Exclusive-OR Gate
General Description
The NC7SZ86 is a single 2-Input Exclusive-OR Gate from
Fairchild’s Ultra High Speed Series of TinyLogic
. The
device is fabricated with advanced CMOS technology to
achieve ultra high speed with high output drive while main-
taining low static power dissipation over a very broad V
CC
operating range. The device is specified to operate over
the 1.65V to 5.5V V
CC
range. The inputs and output are
high impedance when V
CC
is 0V. Inputs tolerate voltages
up to 6V independent of V
CC
operating voltage.

Note 1:
Absolute maximum ratings are DC values beyond which the device
may be damaged or have its useful life impaired. The datasheet specifica-
tions should be met, without exception, to ensure that the system design is
reliable over its power supply, temperature, and output/input loading vari-
ables. Fairchild does not recommend operation outside datasheet specifi-
cations.
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
