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 cur...
