Abstract:
A combination comprising:a signal processing circuit;input terminal means arranged to receive input signals for processing;output terminal means connected to said processing circuit, said processing circuit being selectively operable to process said input signals and provide an output signal at said output terminal means, said output signal being of an electrical state representative of one of a plurality of detectable relationships among the input signals, said processing circuit including an internal node and an output inverter circuit, said output inverter circuit having an input coupled to said internal node, said output inverter circuit further having an inverter output terminal coupled to said output terminal means; anda restoring circuit connected between said output terminal means and said internal node, said restoring circuit being selectively operable in response to an untimely change in said output signal to initiate a circuit operation to restore said output signal to said electrical state which existed prior to said untimely change.
