Abstract: A system operable with any number of different display truth table schemes. The system allows a user to select the truth table scheme and a driver circuit is used to drive either a single or pair of display elements. A binary application select detects a logic 0 if an application sense pin is left floating or is pulled low with a resistor. It detects a logic 1 if the application sense pin is pulled high with a resistor. The sense potential is such that all applications at the pin following reset, namely input or output with connected components will only detect a logic 1 when the pin is pulled high by a pull-up resistor. The output latched application is directed to a responsive circuit operable in a first condition when a logic 0 is detected, and a second condition when a logic 1 is detected. A binary select allows 2n different truth schemes to be selected where n is the number of pins used to select the application. When a first binary code is sensed, a first truth table is implemented.
