8 Detailed Description

8.1 Overview

These hex inverters are designed for 1.65-V to 3.6-V VCC operation. The SN74LVC04A 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.

8.3 Feature Description

Wide operating voltage range from 1.65 V to 3.6 V. Allows down-voltage translation with inputs accept voltages to 3.6 V. IOFF feature supports live insertion, partial power down mode, and back drive protection.
