Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
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
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please

NC7WZ126
TinyLogic UHS Dual Buffer with 3-STATE Outputs
General Description
Features
The NC7WZ126 is a Dual Non-Inverting Buffer with independent active HIGH enables for the 3-STATE outputs. The
Ultra High Speed device is fabricated with advanced
CMOS technology to achieve superior switching performance with high output drive while maintaining low static
power dissipation over a broad VCC operating range. The
device is specified to operate over the 1.65V to 5.5V VCC
operating range. The inputs and outputs are high impedance when VCC is 0V. Inputs tolerate voltages up to 5.5V
independent of VCC operating range. Outputs tolerate voltages above VCC when in the 3-STATE condition.
■ Space saving US8 surface mount package
■ MicroPak Pb-Free leadless package
■ Ultra High Speed; tPD 2.6 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
■ Matches the performance of LCX when operated at
3.3V VCC
■ Power down high impedance inputs/outputs
■ Overvoltage tolerant inputs facilitate 5V to 3V
translation
■ Outputs are overvoltage tolerant in 3-STATE mode
■ 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: The input and output negative voltage ratings may be exceeded is
the input and output diode current ratings are observed.
Note 3: Unused inputs must be held HIGH or LOW. They may not float.

Note 6: 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 = (CPD) (V CC) (fIN) + (ICC static).
