DEFINITION

Classification: 326/40

With flip-flop or sequential device:

(under subclass 39) Subject matter comprising a logic circuit which has two or more distinct current-conductive stable states which toggles from one state to the other in response to an external stimulus or comprising a series connection of such circuits.

(1) Note. A flip-flop is the most common memory element in a sequential circuit which requires storage of previous input information.
