Multiplexer: Comprehensive Global Market Guide for Buyers and Engineers

1. Introduction to Multiplexers

A multiplexer (MUX) is a fundamental electronic device that selects one of several analog or digital input signals and forwards the selected input into a single output line. It is widely used in telecommunications, data acquisition systems, audio/video routing, and digital logic design. The primary function of a multiplexer is to increase the amount of data that can be sent over a network within a certain amount of time and bandwidth. Modern multiplexers are available in various configurations, including 2-to-1, 4-to-1, 8-to-1, and 16-to-1, and are manufactured using CMOS, TTL, and BiCMOS technologies.
