NC7SZ02
TinyLogic
UHS 2-Input NOR Gate
General Description
The NC7SZ02 is a single 2-Input NOR Gate from Fair-
child'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 maintaining
low static power dissipation over a very broad V
CC
operat-
ing range. The device is specified to operate over the 1.8V
to 5.5V V
CC
range. The inputs and output are high imped-
ance when V
CC
is 0V. Inputs tolerate voltages up to 6V
independent of V
CC
operating voltage.

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

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:
