DESCRIPTION/ORDERING INFORMATION (CONTINUED)
To ensure the high-impedance state during power up or power down, OE should be tied to V_CC 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 I_off. The I_off 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.
