Product Introduction

Overview

The 74HCT138PW,112 from Nexperia USA Inc. is a 3-to-8 line decoder/demultiplexer with inverting outputs. This integrated circuit 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 easy parallel expansion and demultiplexing capabilities. The device is part of the 74HCT series, which operates at TTL logic levels, making it compatible with a wide range of applications.
