ON Semiconductor DM74LS253N Dual 4-Input Multiplexer with 3-State Outputs

The ON Semiconductor DM74LS253N is a high-performance, dual 4-input multiplexer with 3-state outputs that is designed to deliver fast and reliable digital switching. Fabricated with Low Power Schottky technology, this integrated circuit is optimized for high-speed operation while maintaining low power consumption.

This multiplexer features two individual 4-input units, each with its own output enable. The device allows one of the four binary inputs to be selected and directed to the output, with the selection determined by the applied control signals. The inclusion of 3-state output capability provides high-impedance outputs, which is beneficial for use in bus-oriented systems where multiple outputs can be connected to a common bus line without interference.

The DM74LS253N is housed in a standard 16-pin DIP (Dual In-line Package), making it compatible with a wide range of through-hole PCB (Printed Circuit Board) designs and easy to integrate into existing systems. The pin configuration is carefully designed to simplify the board layout and minimize signal interference, ensuring reliable operation even in complex digital environments.

Key features of the DM74LS253N include:

• Low power consumption: The device operates efficiently, making it suitable for battery-powered and energy-conscious applications.
• High-speed performance: Its fast switching capability ensures that it can keep up with the demands of high-speed digital systems.
• Wide operating voltage range: The multiplexer can function over a broad range of supply voltages, enhancing its versatility in different circuit configurations.
• 3-State outputs: This feature allows for connection to common bus systems without the risk of data contention or signal corruption.

The ON Semiconductor DM74LS253N is an ideal choice for applications requiring high-speed data selection and routing, such as data processing, communication systems, and complex control panels. Its robust design and reliable performance make it a staple component for engineers and designers looking to build efficient and scalable digital systems.
