will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore

NC7NZ34
TinyLogic UHS Triple Buffer
General Description
Features
The NC7NZ34 is a triple buffer from Fairchild’s Ultra High
Speed Series of TinyLogic in the space saving US8 package. The device is fabricated 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. 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 tolerate voltages up to 7V independent of VCC operating voltage.
■ 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 Drive: ±24 mA at 3V VCC
■ Broad VCC Operating Range: 1.65V to 5.5V
■ Power down high impedance inputs/outputs
■ Overvoltage tolerant inputs facilitate 5V to 3V translation
■ Proprietary noise/EMI reduction circuitry implemented

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 dynamic operating current by the expression:
ICCD = (C PD)(VCC)(fIN) + (ICCstatic).
