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.

Leadless DQFN package
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.
