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
www.onsemi.com.

General Description
The LCX244 contains eight non-inverting buffers with
3-STATE outputs. The device may be employed as a
memory address driver, clock driver and bus-oriented
transmitter/receiver. The LCX244 is designed for low
voltage (2.5V or 3.3V) V
CC
applications with capability of
interfacing to a 5V signal environment.
The LCX244 is fabricated with an advanced CMOS tech-
nology to achieve high speed operation while maintain-
ing CMOS low power dissipation.

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