74HC138D General Description

The 74HC138D is a 3-to-8 line decoder/demultiplexer IC (Integrated Circuit) with three enable inputs and eight output pins. It is commonly used in digital electronic circuits to decode binary information and select one of the eight outputs based on the input signals.The IC operates on a supply voltage range of 2V to 6V and has a low power consumption making it suitable for a variety of battery-powered and low-power applications. The 74HC138D is designed with CMOS technology, providing high speed operation and low power dissipation.The three enable inputs allow for versatile control of the decoder/demultiplexer. The active-low enable inputs enable the selected output when brought to a low logic level. The IC also features a cascading capability, allowing multiple 74HC138D chips to be connected in series to decode larger input combinations.

Key Features

The 74HC138D is a 3-to-8 line decoder/demultiplexer with active high outputs

It has three enable inputs for selecting one of the eight outputs, low power consumption, and high noise immunity

It operates from 2V to 6V supply voltage and has built-in input hysteresis for noise filtering
