DESCRIPTION/ORDERING INFORMATION

This dual bus buffer gate is operational at 0.8-V to 2.7-V VCC, but is designed specifically for 1.65-V to 1.95-V

VCC operation.

The SN74AUC2G126 is a dual bus driver/line driver with 3-state outputs. The outputs are disabled when the

associated output-enable (OE) input is low.

NanoFree? package technology is a major breakthrough in IC packaging concepts, using the die as the

package.

To ensure the high-impedance state during power up or power down, OE should be tied to GND through a

pulldown resistor; the minimum value of the resistor is determined by the current-sourcing capability of the

driver.

This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs,

preventing damaging current backflow through the device when it is powered down.
