These dual 4-input positive-NAND gates are designed for 2-V to 5.5-V VCC operation.
The ’LV20A 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...
