APPLICATION NOTE 955
Analog Switch Expands IC Interface


Abstract:Design idea outlining how to use an IC-controlled analog switch to triple the number of devices connected to an IC
bus.

Perhaps the most effective way to gain board space and increase component density is to minimize wiring on the board. A widely
used architecture that allows such miniaturization is the IC bus. Comprising only a bidirectional data line, SDA, and a clock line,
SCL, this bus requires no chip selects or other additional connections.
