NC7WZ32
TinyLogic UHS Dual 2-Input OR Gate
General Description
The NC7WZ32 is a du al 2-Input OR Gate from Fairch ild’s
Ultra High Speed Series of T inyLogic. The devi ce i s fa br i -
cated with advanced CMOS technology to achieve ultra
high speed with high output drive while maintaining low
static power dissipation over a very broad VCC operating
range. Th e device is s peci f ied to op erate over the 1.6 5V to
5.5V VCC range. The inputs and output are high impedance
when VCC is 0V. Inputs tolerat e volt a ges up to 7V inde pe n-
dent of VCC operating voltage.
Features
■Space saving US8 surface mount package
■MicroPak Pb-Free leadless package
■Ultra high speed tPD 2.4 ns Typ into 50 pF at 5V VCC
■High output driv e ±24 mA at 3V VCC
■Broad VCC operating range 1.65V to 5.5V
■Matches the performance of LCX when operated at
3.3V VCC
■Power down high impedance inputs/output
■Overvoltage tolerant inputs facilitate 5V to 3V translation

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
specifi cations should be met , withou t excep tion, to ensure that the system
design is reliable over its power supply, temperature, and output/input load-
ing variables. Fairchild does not recommend operation outside datasheet
specifications.
Note 2: Unu s ed inputs m ust be he ld H I GH or LOW. They ma y not fl oat.

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 dy namic op erating cu rrent by th e ex pressio n:
ICCD = (CPD) (VCC) (fIN) + (I CCstatic).
