APPLICATION NOTE 4484
In-Circuit Programming Switch
By:Eric Schlaepfer, Applications Engineer


Abstract:A simple bidirectional analog switch (MAX4525) facilitates in-circuit programming by providing dual service for two lines
(SDA and SCL) on the programmable device: for normal operation they connect to other circuitry, and for programming mode
they connect to the programming header.
