DESCRIPTION/ORDERING INFORMATION

This quadruple bus buffer gate is designed for 0.8-V to 2.7-V V_CC operation, but is designed specifically for 1.6-V to 1.95-V V_CC operation.

The SN74AUC125 contains four 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 V_CC 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 I_off. The I_off circuitry disables the outputs, preventing damaging current backflow through the device when it
