Product Introduction

Overview

The 74HC138PW,118 is a 3-to-8 line decoder/demultiplexer integrated circuit produced by Nexperia USA Inc. This device is part of the 74HC series and is designed to decode three binary weighted address inputs (A0, A1, and A2) into eight mutually exclusive outputs (Y0 to Y7). It features three enable inputs (E1, E2, and E3) that allow for multiple enable functions, facilitating easy parallel expansion to a 1-of-32 decoder with just four '138 ICs and one inverter.

The 74HC138PW,118 is housed in a 16-lead TSSOP (Thin Shrink Small Outline Package) and operates over a wide supply voltage range from 2.0 to 6.0 V. It is known for its CMOS low power dissipation, high noise immunity, and robust ESD protection.
