Abstract

IN COMBINATIONAL logic the output of a circuit is determined solely by the state of its inputs at any moment, but in sequential logic the output of a circuit depends on previous inputs as well as present ones; a sequential circuit has memory. The simplest devices with this property which can be used to build much more complicated circuits are called flip-flops. Sequential logic is used to generate a sequence of states in response to a succession of inputs (asynchronous mode) or clock pulses (synchronous mode).
