Abstract: An asynchronous logic circuit is provided having three stable states, namely two information states and a neutral state. Information is transferred between cascaded such circuits wholly under the control of such circuits and at a rate determined by the delay times through various gates. Feedback is employed between each circuit so that for any two given circuits the transfer logic is IN.fwdarw.NI, I representing an information state and N representing the neutral state. Reversible cascaded chains are discussed as well as parallel feed-in and feed-out of information, and fan-in, fan-out and recirculating loops of information. The cascaded circuits (nets) employ interface circuits comprising in most instances a specified part of the basic net circuit.
