The ’LV125A quadruple bus buffer gates are designed for 2-V to 5.5-V VCC operation.
These devices feature 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.
These devices are fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the devices when they are powered down.
