74LCX540 Low Voltage Octal Buffer/Line Driver with 5V Tolerant Inputs and Outputs
March 1995
Revised March 2001
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.
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.
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.
