2 / 13 page www.ti.com DESCRIPTION/ORDERING INFORMATION (CONTINUED) 1 2 7 5 3 6 1A 1Y 2A 2Y 1OE 2OE SN74AUC2G241 DUAL BUFFER/DRIVER WITH 3-STATE OUTPUTS SCES535A – DECEMBER 2003 – REVISED MARCH 2005 To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor, and OE should be tied to GND through a pulldown resistor; the minimum value of the resistor is determined by the current-sinking/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. For more information about AUC Little Logic devices, please refer to the TI application report, Applications of Texas Instruments AUC Sub-1-V Little Logic Devices, literature number SCEA027.
