9 Detailed Description

9.1 Overview

These hex inverters are designed for 2-V to 5.5-V VCC operation. The SN74LV04A devices contain six independent inverters. These devices perform the Boolean function Y = A.

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.

The inputs are high impedance when VCC = 0V.
