SN74LV20A 双路 4 输入正与非门
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 o B o C o 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
