Working Principles

The DG405DY is a digital multiplexer/demultiplexer IC that operates based on the control inputs. When the INHIBIT (INH) pin is low, the SELECT (SEL) pin determines whether the device functions as a multiplexer or demultiplexer. In multiplexing mode, one of the four data inputs (D0-D3) is selected and routed to the common output (COM) based on the binary value applied to the SEL pins. In demultiplexing mode, the input signal is distributed to one of the four outputs (Y0-Y3) based on the SEL pins.

Detailed Application Field Plans

1. Data communication systems: The DG405DY can be used to select different data sources for transmission or distribute incoming data to multiple receivers.
2. Audio/video routing: It can be employed in audio/video switchers to select between various input sources or distribute a single source to multiple outputs.
3. Industrial automation: The IC can be utilized in control systems to route signals from different sensors or actuators to a central processing unit.
4. Test and measurement equipment: It can be integrated into test setups to switch between different test points or distribute test signals to multiple devices.
