Combinational circuits Sequential Circuits
In combinational digital logic circuits don’t have the capability to store a state inside them. In sequential digital logic circuits are capable to retain the earlier state of the system based on the current inputs and earlier state.
The combinational logic circuits do not contain any memory elements. The sequential logic circuits contain memory elements.
The combinational logic circuit’s behavior can be defined by using the set of output functions. The sequential logic circuit’s behavior can be defined by using the set of output functions and set of next state or memory functions.
The combinational logic circuits are independent of the clock. The maximum number of sequential logic circuits uses a clock for triggering the flip flops operation.
