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 down.

2-V to 5.5-V V_CC Operation
Max t_pd of 7 ns at 5 V
