UHS Dual 2-Input OR Gate
General Description
The NC7WZ32 is a dual 2-Input OR Gate from Fairchild's
Ultra High Speed Series of TinyLogic
. The device is fabri-
cated 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
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 7V indepen-
dent 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
specifications should be met, without exception, 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: Unused inputs must be held HIGH or LOW. They may not float.

AC Electrical Characteristics

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
