Abstract : The patent describes a state retention apparatus for a radiation hardened flip flop for protecting the logic circuitry from radiation induced photocurrents. During periods of transient ionizing pulses of a predetermined magnitude, a switching function is performed to protect the logic state of the flip-flop and after the transients have decayed below a predetermined level, the flip-flop is returned to normal operation.
