NC7NZ34 TinyLogic UHS Triple Buffer
July 2001 Revised April 2003
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 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.
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 specifications should be met, without exception, to ensure that the system design is reliable over its power supply, temperature, and output/input loading variables. Fairchild does not recommend operation outside datasheet specifications. Note 2: Unused inputs must be held HIGH or LOW. They may not float.

Note 3: C PD 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 = (CPD)(VCC)(fIN) + (ICCstatic).
