9 Detailed Description

9.1 Overview

This quadruple 2-input positive-AND gate is designed for 2-V to 5.5-V VCC operation. The SN74LA08A device performs the Boolean function eq_1_cls387.gif in positive logic.

This device is fully specified for partial-power-down application 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 input or output when VCC is 0 V
