Working Principles

The MAX4888AETI/V+T operates as a multiplexer/demultiplexer by selectively connecting one of the input channels to the output channel. This is achieved through internal switches controlled by the EN (Enable) and OE (Output Enable) pins. When the EN pin is high, the device is enabled, and the selected input channel is connected to the corresponding output channel. The OE pin controls the output state, allowing the user to enable or disable the output.
