SN74ABT125QDRQ1

四路总线缓冲器闸具有三态输出 QUADRUPLE BUS BUFFER GATE WITH 3-STATE OUTPUTS

description/ordering information

The SN74ABT125Q-Q1 quadruple bus buffer gate features independent line drivers with 3-state outputs. Each output is disabled when the associated output-enable OE input is high.

This device is fully specified for hot-insertion applications using Ioffand power-up 3-state. The Ioffcircuitry disables the outputs, preventing damaging current backflow through the device when it is 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.
