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

The 'LV21A devices perform the Boolean function Y = A • B 1 C • D or Y = (A\ + B\ + C\ + D\)\ in positive logic.

These devices are fully specified for partial-power-down applications using I_off. The I_off circuitry disables the outputs, preventing damaging current backflow through the devices when they are powered down.
