5. Demultiplexer
The chapter discusses key digital components of computers including multiplexers, demultiplexers, arithmetic logic units (ALUs), and the concept of sequential circuits. It delves into how these components operate, their functionalities, and how they are interconnected within a computer system. Additionally, specific focus is given to S-R latches and the challenges of race conditions in digital logic design.

What we have learnt
- Demultiplexers function as reverse multiplexers, transferring input to one of multiple output lines.
- ALUs perform a variety of arithmetic and logical operations, utilizing input signals to determine the operation to execute.
- Sequential circuits maintain outputs based on previous states and are governed by timing signals, specifically clock signals.
Key Concepts
- -- Demultiplexer
- A device that takes a single input line and channels it to one of several output lines based on select signals.
- -- Arithmetic Logic Unit (ALU)
- The fundamental building block of a computer that performs arithmetic and logical operations.
- -- SR Latch
- A storage device that retains output based on input combinations, with particular behavior for set and reset commands.
- -- Sequential Circuit
- A digital circuit whose output depends not only on the present input but also on previous outputs, maintaining state information.
- -- Race Condition
- A situation in digital circuits where the output depends on the sequence or timing of other uncontrollable events.
