DESCRIPTION/ORDERING INFORMATION
This dual bus buffer gate is operational at 0.8-V to 2.7-V V_CC, but is designed specifically for 1.65-V to 1.95-V
V_CC 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 I_off. The I_off circuitry disables the outputs,
preventing damaging current backflow through the device when it is powered down.
