Not a Sequential Circuit:
Sequential circuits are circuits where the output not only depends on the current input but also on the past sequence of inputs. Among the options provided, the one that is not a sequential circuit is a Multiplexer.
Explanation:
- Flip-flop: A flip-flop is a basic building block of sequential circuits. It stores a single bit of data and is used to store state information.
- Counter: A counter is a sequential circuit that counts the number of clock cycles and generates a series of output states based on the count value.
- Shift register: A shift register is a sequential circuit that stores and shifts data in a controlled manner.
- Multiplexer: A multiplexer is a combinational circuit that selects one of several input data lines and forwards it to a single output line based on the select lines' values. It does not have any memory elements to store past inputs.
Therefore, a multiplexer is not a sequential circuit as it does not have any memory elements to retain past input information.

- Combinational logic is a type of digital logic that is implemented by Boolean circuits, where the output is a pure function of the present input only.
- Sequential logic is a type of digital logic in which the output depends not only on the present input but also on the history of the output.
- Sequential logic has memory while combinational logic does not.
- Flip-flop, counter, and shift registers are sequential circuits whereas multiplexer, decoder, and encoder act like combinational circuits.
