NC7WZ125

TinyLogic UHS Dual Buffer with 3-STATE Outputs

General Description

Features

The NC7WZ125 is a Dual Non-Inverting Buffer with inde-

pendent active LOW enables for the 3-STATE outputs. The

Ultra High Speed device is fabricated with advanced

CMOS technology to achieve superior switching perfor-

mance with high output drive while maintaining low static

power dissipation over a broad V_CCoperating range. The

■ Space saving US8 surface mount package

■ MicroPak leadless package

■ Ultra High Speed; t_PD2.6 ns typ into 50 pF at 5V V_CC

■ High Output Drive; ±24 mA at 3V V_CC

■ Broad V_CCOperating Range; 1.65V to 5.5V

device is specified to operate over the 1.65V to 5.5V V_CC

■ Matches the performance of LCX when operated at

3.3V V_CC

operating range. The inputs and outputs are high imped-

ance when V_CCis 0V. Inputs tolerate voltages up to 5.5V

■ Power down high impedance inputs/outputs

independent of V_CCoperating range. Outputs tolerate volt-

ages above V_CCwhen in the 3-STATE condition.

■ 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 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: The input and output negative voltage ratings may be exceeded if

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: C_PDis defined as the value of the internal equivalent capacitance which is derived from dynamic operating current consumption (I_CCD) at no output

loading and operating at 50% duty cycle. (See Figure 2.) C_PDis related to I_CCDdynamic operating current by the expression:

I_CCD= (C_PD)(V_CC)(f_IN) + (I_CCstatic).
