These triple 3-input positive-NOR gates are designed for 2-V to 5.5-V VCC operation.
The ’LV27A devices perform the Boolean function Y = A + B + C or Y = A
- B
- C 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...
