Abstract
A flip-flop including a master section having an input for receiving a data signal and a pair of outputs, one output for providing the data signal state, and one output for providing the data signal state complement, and a slave section having a pair of inputs, one connected to each of the outputs of the master section, and a pair of outputs, one of the outputs of the slave section for providing the data signal state, and one of the outputs of the slave section for providing the data signal state complement. A cross coupling circuit is provided in the slave section for connecting the slave section input for receiving the data signal state to the slave section output for providing the data signal state, and for connecting the slave section input for receiving the data signal state complement to the slave section output for providing the data signal state complement. Pass means are provided in the cross coupling circuit for controlling coupling between the slave section outputs and the slave section inputs, and a clock is provided for controlling the master section and the pass means such that the pass means decouples the cross coupling circuit when the data state and data state complement are provided by the master section outputs to the slave section inputs.
