description/ordering information
This quadruple bus buffer gate is designed for
1.65-V to 3.6-V V
CC
operation.
The SN74LVC125A features independent line
drivers with 3-state outputs. Each output is
disabled when the associated output-enable (OE)
input is high.

To ensure the high-impedance state during power up or power down, OE should be tied to V
CC
through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of this device as a translator
in a mixed 3.3-V/5-V system environment.
