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

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
providing flow-through architecture (inputs on opposite
side from outputs). This pinout arrangement makes this
device especially useful as an output port for micropro-
cessors, 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 dissipa-
tion.

Note:
1. To ensure the high impedance state during power up
or down, OE should be tied to V
CC
through a pull-up
resistor: the minimum value of the resistor is
determined by the current-sourcing capability of the
driver.
