NC7WZ240

TinyLogic

 UHS Dual Inverting Buffer

with 3-STATE Outputs

General Description

The NC7WZ240 is a Dual Inverting Buffer with indepen-

dent 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

operating range. The

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

operating range. The inputs and outputs are high imped-

ance when V

is 0V. Inputs tolerate voltages up to 5.5V

independent of V

operating range. Outputs tolerate volt-

ages above V

when in the 3-STATE condition.

Features

■ Space saving US8 surface mount package

■ MicroPak

 Pb-Free leadless package

■ Ultra High Speed; t

2.3 ns typ into 50 pF at 5V V

■ High Output Drive; ±24 mA at 3V V

■ Broad V

Operating Range: 1.65V to 5.5V

■ Matches the performance of LCX when operated at

3.3V V

■ Power down high impedance inputs/outputs

■ Overvoltage tolerant inputs facilitate 5V to 3V translation

■ Outputs are overvoltage tolerant in 3-STATE mode
