† 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  onditions 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.

These dual 4-input positive-NAND gates of LV20A are designed for 2-V to 5.5-V V_CC operation.

The 'LV20A devices perform the Boolean function Y = A • B • C • D or Y = A + B + C + D in positive logic.

LV20A is 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.
