Signal Switches, Multiplexers, and Decoders are used for signal routing, selection, and decoding in electronic systems. Signal Switches allow the routing of signals between different paths or channels, Multiplexers enable the selection of one of several input signals to a single output, and Decoders convert coded inputs into specific outputs based on predefined logic. These ICs are widely used in communication systems, digital circuits, data acquisition systems, and control applications to manage signal paths, data selection, and logic operations efficiently. Basic ICs with fewer channels and simpler functionality are generally more affordable. High-performance ICs with multiple channels, advanced features like low on-resistance, wide bandwidth, and enhanced reliability may command higher prices. When purchasing these ICs, determine the required number of channels, input/output configurations, and operating parameters (voltage, frequency) based on your system's signal routing or logic operation needs. Select ICs with suitable specifications for signal bandwidth, switching speed, and input/output voltage levels to ensure compatibility and performance.
