The sequential circuit is a special type of circuit that has a series of inputs and outputs. The outputs of the sequential circuits depend on both the combination of present inputs and previous outputs.
• The previous output is treated as the present state. So, the sequential circuit contains the combinational circuit and its memory storage elements.
• A sequential circuit doesn’t need to always contain a combinational circuit. So, the sequential circuit can contain only the memory element.
Difference between the combinational circuits and sequential circuits are given below:
Latches:
A latch is a bistable digital circuit, meaning it has two stable states. It is used to store a single bit of information and hold its value until it is updated by new input signals.
• Latches and flip-flops are both bistable devices, meaning they have two stable states. This means that they can store a single bit of information and hold its value until it is updated by new input signals.
• Latches and flip-flops are also both made up of logic gates.
• The main difference between latches and flip-flops is that latches are level-triggered, while flip-flops are edge-triggered.
