74LCX540

Low Voltage Octal Buffer/Line Driver

with 5V Tolerant Inputs and Outputs

General Description

The LCX540 is an octal buffer/line driver designed to be

employed as a memory and address driver, clock driver

and bus oriented transmitter/receiver.

Features

■ 5V tolerant inputs and outputs

■ 2.3V–3.6V V_CCspecifications provided

■ 6.5 ns t_PDmax (V_CC3.3V), 10 A I_CCmax

This device is similar in function to the LCX240 while pro-

viding flow-through architecture (inputs on opposite side

from outputs). This pinout arrangement makes this device

especially useful as an output port for microprocessors,

allowing ease of layout and greater PC board density.

■ Power down high impedance inputs and outputs

■ Supports live insertion/withdrawal (Note 1)

■ Implements patented noise/EMI reduction circuitry

■ Latch-up performance exceeds JEDEC 78 conditions

■ ESD performance:

The LCX540 is designed for low voltage (2.5V or 3.3V) V_CC

applications with capability of interfacing to a 5V signal

environment. The LCX540 is fabricated with an advanced

CMOS technology to achieve high speed operation while

maintaining CMOS low power dissipation.

Human body model 2000V

Machine model 200V

■ Leadless Pb-Free DQFN package

Note 1: To ensure the high-impedance state during power up or down, OE

should be tied to V

through a pull-up resistor: the minimum value or the

resistor is determined by the current-sourcing capability of the driver.
