Application information

The switch can be used in a wide array of applications as shown in the below section. The

only difference is the way the switching is accomplished (mux or de-mux) and the type of

signals which are needed by different applications.

4.2

Notebook

In a PC application, the video switch can be used to multiplex RGB signals between a

notebook and its docking station. Use of a 3-bit/3-channel SPDT analog video switch in this

application eliminates a redundant graphics chip in the docking station, thus reducing cost,

component count and complexity.
