OMAR: In multiplex configurations a switch (either mechanical or solid state) selects the routing of the signal. To avoid signal contention due to more than one signal active simultaneously, the [resent signal is discontinued (the switch breaks) before the next signal is placed on the line (The switch makes). If you look in the data books for analog multiplexers you will usually find excellent timing diagrams and literal description. Try a search for analog multiplexers at Analog Devices, or National or others. Digital information is also multiplexed and similar rules apply. But there are also make before break configurations. Let me know if you would like more definition. ----- Original Message ----- From: "Omer YALHI" To: "'Microcontroller discussion list - Public.'"
