description/ordering information
These dual 4-input positive-AND gates are
designed for 2-V to 5.5-V VCC operation.
The ’LV21A devices perform the Boolean function
Y + A B C D or Y + A ) B ) C ) D in
positive logic.
These devices are fully specified for
partial-power-down applications using Ioff. The Ioff
circuitry disables the outputs, preventing
damaging current backflow through the devices
when they are 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. This value is limited to 5.5 V maximum.
3. The package thermal impedance is calculated in accordance with JESD 51-7.
