9 Detailed Description

9.1 Overview

The SN74LV02A devices are quadruple 2-input positive-NOR gates designed for 2-V to 5.5-V VCC operation.

The SN74LV02A devices perform the Boolean function Y = A + B or Y = A ● B 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.

9.3 Feature Description

  • Wide operating voltage range
    • Operates from 2 V to 5.5 V
  • Allows down voltage translation
    • Inputs accept voltages to 5.5 V
  • Ioff feature allows voltages on the inputs and outputs when VCC is 0 V
