Working Principles

The HEF4051BT,013 is an analog switch that operates as a multiplexer or demultiplexer. It uses digital control signals (S0, S1, and S2) to select one of the eight input channels (A0, A1, and A2) and connect it to the output pin (Y). The enable pin (E) controls the on/off state of the switch.

When a specific combination of control signals is applied, the corresponding input channel is connected to the output pin, allowing the passage of analog signals. This enables the HEF4051BT,013 to perform signal routing and selection in various applications.
