Product Introduction

Overview

The 74HC138D/AU118, produced by Nexperia USA Inc., is a 3-to-8 line inverting decoder/demultiplexer. This CMOS device decodes three binary weighted address inputs (A0, A1, and A2) to eight mutually exclusive outputs (Y0 to Y7). It features three enable inputs (E1, E2, and E3), allowing for flexible control and expansion capabilities. The device is suitable for a wide range of applications, including memory chip select decoding, demultiplexing, and single line peripheral control.
