Analog switches, multiplexers, and demultiplexers are a type of device that takes one or more analog input signals and selectively routes them to multiple output signals. One of the most popular devices of this type is the MAX391CPE. This device is designed for low-voltage single-supply applications, and provides high-speed switching and low-on-resistance. It is a high-performance CMOS analog multiplexer/demultiplexer that can switch signals up to 300MHz.

The MAX391CPE works by providing a digital control signal to its select inputs to control the internal analog switch. When a control signal is applied, the MAX391CPE selects one of the analog input signals and routes it to the output. This is done by switching on the internal relay-like structure known as an analog switch, which is the basic element of the device.

The MAX391CPE is ideal for use in applications where low-voltage, single-supply operation is required and high-speed switching and low-on-resistance is needed. Examples of these applications include audio switching, video switching, amplifier switching, data acquisition systems, instrumentation, and medical applications. The device also features a low 6-mV hysteresis to ensure accurate control and low-voltage operation. The device is available in compact 8-pin packages, making it easy to use in limited space applications.

The MAX391CPE is a pin-compatible replacement for the MAX391, and offers improved operational performance at lower power consumption. It is designed for applications which require a high degree of speed and accuracy. In addition, the MAX391CPE has an output enable (OE) pin which can be used to turn off the output to minimize power consumption. The device also features an open-drain output which can be used to create a non-inverting logic output.

The MAX391CPE has been designed to provide superior performance, reliability and low-current consumption. The device is well suited for a wide range of applications, from audio and video switching to data acquisition systems and instrumentation. Its high-speed switching and low-on-resistance make it an ideal choice for applications which require reliable and accurate control.
