A triggerable latch using a "Hybrid-mode" MOSFET bistable circuit

The potentialities which result from exploiting both types of conduction mechanism (majority and minority carriers) possible with an insulated-gate FET are exemplified in the design of a simple "hybrid-mode" regenerative circuit constituting a triggerable latch, which is switched on following the closure of two contacts and switched off via a separate input. The circuit is TTL-logic compatible and useful for such applications as touch-sensitive switching.
