DESCRIPTION/ORDERING INFORMATION
The SN74LV125AT is a quadruple bus buffer gate. This device 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 VCC through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs,
preventing damaging current backflow through the device when it is powered down.
