DM74S138N Decoder/Demultiplexer by ON Semiconductor

The DM74S138N is a high-performance integrated circuit designed and manufactured by ON Semiconductor, a leader in energy-efficient innovations. This decoder/demultiplexer is part of the 74S series logic family, known for its speed and reliability in a wide range of digital applications.

The DM74S138N is a 3-to-8 line decoder/demultiplexer with inverting outputs. It is designed to accept three binary weighted inputs (A0, A1, and A2) and, when enabled, provides eight mutually exclusive active-LOW outputs (O0 to O7). The device features three enable inputs: two active-LOW (E1, E2) and one active-HIGH (E3). The DM74S138N performs the demultiplexing function by distributing data from an input to any one of the eight outputs. Its decoding and demultiplexing capabilities make it suitable for a variety of applications, including data routing, memory addressing, and control signal generation.

Constructed with NPN silicon gate technology, the DM74S138N is characterized by a significant reduction in power consumption when compared to its TTL counterparts, while maintaining the ability to drive the same load types. This makes it an excellent choice for high-speed operation and power-sensitive applications.

The device is typically housed in a 16-pin plastic DIP (Dual In-line Package), which is easy to handle and integrate into a variety of electronic systems. Its pin configuration is designed for straightforward PCB (Printed Circuit Board) layout, contributing to ease of design and implementation in complex circuits.

Key features of the DM74S138N include:

• Designed for high-speed applications
• Power dissipation typically 130 mW
• Decoding and demultiplexing capabilities
• Wide operating voltage range
• High noise immunity
• Low power Schottky technology

Overall, the DM74S138N from ON Semiconductor is a versatile and efficient solution for designers looking to implement decoding or demultiplexing functions in their digital systems. Its robust design and compatibility with other logic families make it a popular choice for modern electronic applications.
