DM74LS139N

The DM74LS139N is an Integrated Circuit (IC) component that belongs to the LS family of TTL logic chips. It is a dual 2-to-4 line decoder/demultiplexer designed for high-speed memory decoding or data routing applications. Below is a concise overview and key features of the DM74LS139N: 1. Overview: - The DM74LS139N consists of two independent 2-to-4 line decoders enclosed in a single 16-pin DIP (Dual In-line Package). - Each decoder has two select inputs, A and B, and four outputs (Y0, Y1, Y2, and Y3). - The chip can be used to generate four distinct outputs by selecting one of the four combinations of input signals. 2. Key Features: - High-Speed Operation: The DM74LS139N is designed to operate at a high switching speed, allowing for efficient decoding or demultiplexing of input signals. - Active-Low Output Enable Inputs: The active-low G1 and G2 inputs allow the user to disable the outputs, making it suitable for multiplexing applications. - Multiple Package Options: The DM74LS139N is available in various package options, including DIP and SOIC, providing flexibility for different design requirements. - Wide Operating Voltage Range: The chip can handle a wide range of operating voltages, typically from 4.75V to 5.25V, making it compatible with different systems
