DUAL 2INPUT NAND GATE

WITH OPEN DRAIN OUTPUT

SCES554A − MARCH 2004 − REVISED OCTOBER 2004

POST OFFICE BOX 655303

• DALLAS, TEXAS 75265

description/ordering information (continued)

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.

† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and

functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not

implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTES:

1. The input and output negative-voltage ratings may be exceeded if the input and output current ratings are observed.

2. The value of VCC is provided in the recommended operating conditions table.

3. The package thermal impedance is calculated in accordance with JESD 51-7.
