ABSTRACT:
A hazard-free latch is disclosed comprising three NAND logic gates, one of the gates, in combination with its output loading, being relatively fast and another of the gates, in combination with its output loading, being relatively slow. Both gates receive an input clock signal. Input data is applied to the third gate. The output of the fast gate is connected to another input of the slow gate. The outputs of the third and the slow gates are connected to an output terminal and to another input of the fast gate.
