Working Principles

The MC74HC4852AN is a CMOS analog multiplexer/demultiplexer. It operates by selectively connecting one of the eight input channels to the common output terminal based on the control signals provided. The INHIBIT pin is used to enable or disable the device, while the CHANNEL pins determine the desired channel.

When the INHIBIT pin is low, the device is enabled, and the selected channel is connected to the common terminal. When the INHIBIT pin is high, all channels are disconnected from the common terminal.
