Product Summary
The SN74ABT125N is a quadruple bus buffer gate. The SN74ABT125N features independent line drivers with 3-state outputs. Each output is disabled when the associated output-enable (OE) input is high. The SN74ABT125N is fully specified for hot-insertion applications using Ioff and power-up 3-state. The Ioff circuitry disables the outputs, preventing damaging current backflow through the devices when they are powered down. The power-up 3-state circuitry places the outputs in the high-impedance state during power up and power down, which prevents driver conflict. 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.
