The MAX399EPE+ is a monolithic CMOS Analogue multiplexer/demultiplexer and logic switch. It is designed for maximum performance, low cost and relatively low on power consumption and electronic noise, making it a great choice among the available options for many different applications.

Designed for a wide voltage range from a single 2.7 V to 5.5 V supply, the MAX399EPE+ provides a single-channel low-glitch, low-capacitance, and low-on-resistance multiplexer/demultiplexer that can operate in both analogue mode as well as TTL logic switch mode. This device is ideal for multiplexing and demultiplexing high-frequency analogue signals or low-frequency digital signals.

The MAX399EPE+’s multiplexer/demultiplexer function consists of one control line and one data line. When the control line (S) is left open or driven high, the signal at the data line (D) is passed through with minimal signal distortion and low-capacitance loading. When the control signal (S) is driven low, the multiplexer/demultiplexer is tri-stated and no signal passes through. The data line (D) can be either an analogue signal or a TTL-level digital signal.

The MAX399EPE+ also has a TTL switch function which allows for switching of TTL logic signals. It features an internal logic-level clamping circuit, which reduces possible interference from digital signals and static noise. This device also includes integrated protection circuitry, which automatically clamp the input signals to prevent the possibility of over-leveled input signals.

In applications where the switching of analogue signals is required, the MAX399EPE+ eliminates the need for individual switch components or external capacitors or resistors. It allows for easy switch control with a single input line and can greatly reduce overall circuit complexity. It can also reduce power consumption in portable devices as compared to other switching methods due to it’s low-on-resistance and low power requirements.

The MAX399EPE+ is an ideal choice for any application requiring analogue multiplexing/demultiplexing, or switching of TTL or CMOS logic levels. Its low power dissipation, low noise production, and low-input capacitance make it a great choice for applications that require low-power, low-noise operation in a relatively small package.
