NC7WZ32
TinyLogic UHS Dual 2-Input OR Gate
General Description
Features
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 VCC operating
■ Space saving US8 surface mount package
■ MicroPak leadless package
■ Ultra high speed tPD 2.4 ns Typ into 50 pF at 5V VCC
■ High output drive ±24 mA at 3V VCC
range. The device is specified to operate over the 1.65V to
5.5V VCC range. The inputs and output are high impedance
■ Broad VCC operating range 1.65V to 5.5V
■ Matches the performance of LCX when operated at
3.3V VCC
when VCC is 0V. Inputs tolerate voltages up to 7V indepen-
dent of VCC operating voltage.
■ Power down high impedance inputs/output
■ Overvoltage tolerant inputs facilitate 5V to 3V translation
■ Patented noise/EMI reduction circuitry implemented
