NC7S02
TinyLogic 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 hi gh speed and low po wer cir cuit oper ation ove r a
broad VCC range. ESD protection diodes inherently guard
both inputs and output with respect to the VCC and GND
rails. Three stages of gain between inputs and outputs
assures high noise immunity and reduced sensitivity to
input edge rate.

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, temperatu re, and output /input lo ading variable s. Fairch ild do es not

AC Electrical Characteristics
Note 3: CPD is defined as the value of the internal equivalent capacitance which is derived from dynamic operating current consumption (ICCD) at no output
loading and operating at 50% duty cycle. (See Figure 2.) CPD is related to ICCD dynam ic operating current by th e ex pression:
ICCD = (CPD)(VCC)(fIN) + (I CCstatic).
