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 LCX126 contains four independent non-inverting
buffers with 3-STATE outputs. Each output is disabled
when the associated output-enable (OE) input is LOW.
The inputs tolerate voltages up to 7V allowing the inter-
face of 5V systems to 3V systems.
The 74LCX126 is fabricated with an advanced CMOS
technology to achieve high speed operation while main-
taining 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 of the resistor is
determined by the current-sourcing capability of the
driver.
