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.
General Description
The LCX125 contains four independent non-inverting
buffers with 3-STATE outputs. The inputs tolerate volt-
ages up to 7V allowing the interface of 5V systems to 3V
systems.
The 74LCX125 is fabricated with an advanced CMOS
technology to achieve high speed operation while main-
taining CMOS low power dissipation.
