UHS 2-Input NOR Gate
General Description
The NC7SZ02 is a single 2-Input NOR Gate from Fairchild’s Ultra High Speed Series of TinyLogic
. The device
is fabricated with a dvanced CMOS technolo gy to achieve
ultra high speed with high outpu t drive while maintaining
low static power dissipa tion over a ver y broa d V
CC
operat-
ing range. The device is specified to opera te over the 1.8V
to 5.5V V
CC
range. The inputs an d output ar e high im ped-
ance when V
CC
is 0V. Inputs tolerate voltages up to 6V
independent of V
CC
operating voltage.
Features

Absolute Maximum Ratings(Note 1) Recommended Operating
Conditions
(Note 2)
Note 1: Absolute maximum ratings are DC values beyond which the device
may be damage d or h ave its us eful life im paired . T he data shee t s pec ific ations should be met, without exception, to ensure that the system design is
reliable over its power supply, temperature, and output/input loading variables. Fairchild does no t recommend operation outsid e datasheet spec ifications.
Note 2: Unused inputs must be held HIGH or LOW. They ma y not float.

AC Electrical Characteristics
Note 3: CPD 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
