NC7NZ34
TinyLogic UHS Triple Buffer
General Description
The NC7NZ34 is a triple buffer from Fairchild’s Ultra High
Speed Series of TinyLogic in the space saving US8 pack-
age. The device is fabricated with advanced CMOS tech-
nology to achieve ultra high speed with high output drive
while maintaining low static power dissipation over a very
broad VCC operating range. The device is specified to
operate over the 1.65V to 5.5V VCC range. The inputs and
outputs are high impedance when VCC is 0V. Inputs toler-
ate voltages up to 7V independent of VCC operating volt-
age.
Features
s Space saving US8 surface mount package
s MicroPak leadless package
s Ultra High Speed: tPD 2.4 ns Typ into 50 pF at 5V VCC
s High Output Drive: ±24 mA at 3V VCC
s Broad VCC Operating Range: 1.65V to 5.5V
s Power down high impedance inputs/outputs
s Overvoltage tolerant inputs facilitate 5V to 3V translation
s Patented noise/EMI reduction circuitry implemented

Note 1: Absolute maximum ratings are DC values beyond which the device
may be damaged or have its useful life impaired. The datasheet specifica-
tions should be met, without exception, to ensure that the system design is
reliable over its power supply, temperature, and output/input loading vari-
ables. Fairchild does not recommend operation outside datasheet specifi-
cations.
Note 2: Unused inputs must be held HIGH or LOW. They may not float.
