Circuit Principle and Application:

The 74HC4053D is a triple 2-channel analog multiplexer/demultiplexer. It uses digital control signals to select one of the three input channels (A, B, C) and route it to a common output. The multiplexer also supports bidirectional switching, meaning it can both send and receive signals, making it suitable for audio, video, and data routing applications. The device is typically used in systems that require switching of analog signals or digital signals over different channels.

It has three independent 2-channel multiplexer circuits, and each has one common pin (COM) and two selectable inputs (Y, Z, W). The IC's three multiplexers allow the user to route multiple signals to the same output channel using a control mechanism based on the select pins (S1, S2, S3).
