Working Principle:

The DG9425EDQ-T1-GE3 operates as a quad SPST switch, meaning it contains four independent Single-Pole Single-Throw switches within a single IC package.

  • Single-Pole: Each switch has a single input terminal and a single output terminal.

  • Single-Throw: The switch can be in one of two states: open or closed. In the closed state, the input terminal is connected to the output terminal, allowing current to flow. In the open state, the connection is broken, preventing current flow.

  • Control Inputs: The IC will have control inputs that allow you to selectively enable or disable each switch independently.

  • Working Process: When a specific control input is activated, the corresponding SPST switch will change its state, either connecting or disconnecting the input signal to the output as per the design requirements.

By using the control inputs to manipulate the states of the individual switches, the IC manages the routing of signals within a circuit, enabling various functionalities such as signal selection, isolation, or connection in electronic systems depending on the specific application needs.
