Характеристики
SN74ABT125D, ЛП8The SN74ABT125D is a 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 IOFF and power-up 3-state. The IOFF circuitry disables the outputs, preventing damaging current backflow through the devices 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. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pull-up resistor, the minimum value of the resistor is determined by the current-sinking capability of the driver.
