DG442LAK

Introduction

The DG442LA series of analog multiplexers (MUX) consists of four high-speed CMOS analog multiplexers as well as demultiplexers. This series is used in systems that need to switch, mix, or route signals between different points. It provides excellent isolation and low glitch energy. The DG442LA series also provides a wide choice of access times, flexible logic levels, and single-ended and differential logic types. In addition, this series is durable, having been designed to withstand high-speed, high-temperature, and vibration-proof applications.

Application Field

The DG442LA series is most commonly used in signal switching, mixing, and routing applications. It is especially useful in telecommunications, test and measurement, and instrumentation and control systems. Additionally, it can be used in a wide variety of other applications where switching and routing of signals is needed.

Working Principle

The working principle of the DG442LA series is fairly simple. This series uses CMOS analog multiplexers to switch, mix, or route signals between different points. Each multiplexer is composed of four differential, CMOS switches, providing excellent isolation and low glitch energy. Additionally, each switch can be controlled by separate enable or disable lines.

The DG442LA series also offers a wide selection of access times, logic types, and logic levels. The access time is the amount of time it takes for the multiplexer to switch between channels and can range from 1 to 22 nanoseconds. The logic types, on the other hand, include single-ended and differential, while the logic levels range from standard TTL to 3.3, 5, and 12V.

In addition, the DG442LA series is designed to withstand high-speed and high-temperature applications and is resistant to vibration. The multiplexers also require minimal static power and no precharge is needed upon power-up. Finally, the series is also ESD protected and has protection against latch-up.

Conclusion

The DG442LA series of analog multiplexers is a versatile and durable series that can be used for signal switching, mixing, and routing applications. It is composed of four differential, CMOS switches and it offers a wide variety of access times, logic types, and logic levels. Additionally, the series is designed to withstand high-speed, high-temperature, and vibration-proof applications and is ESD protected.
