Abstract (en)

[origin: WO0147112A2] A bistable device has first and second complementary input terminals and first and second bistable states that are determined by the polarity of the signal applied to one of the input terminals. A source of an uninverted binary input signal, preferably an uninverted data stream, has a first value of a second value. A source of an inverted binary input signal, preferably an inverted data stream, has a first value or a second value in complementary relationship to the values of the uninverted input signal. A first source of a trigger signal has one polarity. A second source of a trigger signal has the other polarity. The first trigger signal is applied to the first input terminal and the second trigger signal is applied to the second input terminal to drive the bistable device into the first stable state when the input signal has the first value. The first trigger signal is applied to the second input terminal and the second trigger signal is applied to the first input terminal to drive the bistable device into the second stable state when the input signal has the second value.
