Abstract

Abstract FIRST AND SECOND METAL INSULATOR SEMICONDUCTOR FIELD-EFFECT TRANSISTORS (MIS-FET''S) HAVE THEIR SOURCES CONNECTED TOGETHER AND TO AN INPUT, AND THEIR DRAINS CONNECTED TO SEPARATE OUTPUTS, TO CONSTITUTE TRANSFER CONTACTS OF A RELAY. THE TRANSISTORS ARE CONTROLLED BY A PAIR OF MIS-FET SWITCHES EACH HAVING TWO INPUTS AND AN OUTPUT. THE FIRST SWITCH HAS ONE INPUT CONNECTED TO A CONTROL TERMINAL AND ITS OUTPUT CONNECTED BOTH TO ONE INPUT OF THE SECOND SWITCH AND TO THE GATE OF THE FIRST TRANSISTOR. THE GATE OF THE SECOND TRANSISTOR CAN BE CONNECTED EITHER TO THE CONTROL INPUT (PROVIDING, E.G., EARLY MAKE-BREAK OPERATION) OR TO THE OUTPUT OF THE SECOND SWITCH (PROVIDING, E.G., EARLY BREAK-MAKE OPERATION). IN THE LATTER CASE THE SECOND SWITCH OUTPUT CAN ALSO BE CONNECTED TO THE SECOND INPUT OF THE FIRST SWITCH, PROVIDING LATCHING OPERATION, IN WHICH CASE THE RELAY IS RESET BY A RESET VOLTAGE APPLIED TO THE SECOND INPUT OF THE SECOND SWITCH.
