6.1 Overview

The SN74LV20A devices perform the Boolean function Y = A • B • C • 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.
