概述

Description

The CD74HC138M96 is a high-speed CMOS 3-to-8 line decoder/demultiplexer. It decodes a 3-bit binary input into one of eight active low outputs. The device features three enable inputs (G1, G2A, G2B) which allow for flexible control of the output activation. When enabled, a high logic level on the input selects one of the eight outputs, while all other outputs remain low.
The CD74HC138M96 operates at a wide voltage range, typically from 2V to 6V, making it suitable for various digital applications. It provides low power consumption, fast switching times, and high noise immunity, making it ideal for use in communication systems, data routing, and memory address decoding.
The package type (M96) refers to a specific surface-mount technology (SMD) configuration, ensuring compact integration into circuits. Overall, the CD74HC138M96 is an essential component in digital logic design, enabling efficient data management and routing in electronic systems.

Features

The CD74HC138M96 is a high-speed CMOS 3-to-8 line decoder/demultiplexer. Key features include:
