These triple 3-input positive-NAND gates are designed for 2-V to 5.5-V V_CC operation. The SN74LV10A devices perform the Boolean function Y = A • B • C 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.
