A LOGICAL COINCIDENCE GATE COMPRISING, A TUNNEL DIODE HAVING A REVERSE BIAS STATE, A LOW CURRENTLOW VOLTAGE STATE, A HIGH CURRENT-LOW VOLTAGE STATE, AND A HIGH VOLTAGE STATE, SAID TUNNEL DIODE CONNECTED TO BE RESPONSIVE TO THREE LOGICAL INPUTS, MEANS FOR BIASING SAID TUNNEL DIODE TO ITS REVERSE BIAS STATE IN THE ABSENCE OF ANY SIGNALS FROM SAID LOGICAL INPUTS, THE PRESENCE OF A SIGNAL FROM ANY ONE OF SAID LOGICAL INPUTS SWITCHING SAID TUNNEL DIODE FROM ITS REVERSE BIAS STATE TO ITS LOW CURRENT-LOW VOLTAGE STATE, THE PRESENCE OF COINCIDENCE SIGNALS FROM ANY TWO OF SAID LOGICAL INPUTS SWITCHING SAID TUNNEL DIODE FROM ITS REVERSE BIAS STATE TO ITS HIGH CURRENT-LOW VOLTAGE STATE, AND THE PRESENCE OF COINCIDENCE SIGNALS FROM ALL THREE OF SAID LOGICAL INPUTS SWITCHING SAID TUNNEL DIODE FROM ITS REVERSE BIAS STATE TO ITS HIGH VOLTAGE STATE, AND A TRANSISTOR CIRCUIT CAPABLE OF BEING BIASED TO CONDUCTIVE AND NON-CONDUCTIVE STATES CONNECTED TO SAID TUNNEL DIODE SUCH THAT SAID TRANSISTOR CIRCUIT SWITCHES ITS STATE IN RESPONSE TO SAID TUNNEL DIODE SWITCHING TO ITS HIGH VOLTAGE STATE.
