In general, a sequential circuit is a circuit that depends on a previous state. That means it needs to have some sort of "memory". As the name may suggest, sequence detectors are a good example of a sequential circuit. As bits (1's and 0's) are inputted, it can determine if a certain sequence has been detected. So as each bit gets inputted, it will need to remember it as it gets the next bit. You would need various IC's to create a sequential circuit; most importantly, a memory element of some sort, like a flip-flop.
both combinational and sequential circuits have two inputs and outputs..!
To check the IC by the multimeter, you have to make sure that the pointer points at the current. You can then connect the multimeter across the check the IC.
i would never naturally assume any circuitry to be "reverse polarity" by default even if they are. since this can fry a lot of IC, and micro controllers. there are several options to adding a reverse polarity protection circuit to your project you can find three easy to implement circuits here: http://provideyourown.com/2012/reverse-polarity-protection-circuits/
parallel circuits can be used for lots of things.Things such as : . Christmas tree lights False for A+
LM stands for "NATIONAL SEMICONDUCTORS". i.e, that particular ic has been manufactured by "NATIONAL SEMICONDUCTORS". infact on any ic two letters indicate the manufacturing company's name,eg MC stands for Motorola(now freescale),SN for Texas instruments,NS for signetics, CM for California microelectronics and so on...
how to implement sequential circuit that counts up and down using 74393 IC
A circuit is a plan of exercises one does to get fit and a sequential circuit is a set of these one does one after the other, it is called circuit training.
Advantages of sequential circuits
Sequential Logic circuits are a type of logic circuits in which its output depends on the current and last input (memory). a digital circuits that contain filp-flop is called as sequential ckt because its output at any time depend not only on its current input but also past sequence memory of past event.
combinational circuit
Washing machines, dryers, dishwashers.
A sequential circuit is a type of logic circuit. It sends an output that is dependent upon the present input in addition to the history of the input. That makes it different from a combinational circuit, whose output depends solely on the present input. Given their reliance on input history (or stored input), sequential circuits are particularly useful in computer random access memory (RAM). The two types of sequential circuits are synchronous circuits and asynchronous circuits.
hazards in combinational and sequential circuits
Asynchonous sequential logic circuits
This difficulty arises due to the fact that the IC fabrication techniques are layer oriented which typically involve processes which are applied to multiple horizontal surfaces in a sequential fashion. However the inductive circuits has a "non-planar" configuration which typically has a continuous spiral shape. This particular spiral configuration thus prevents the IC fabrication to integrate the inductive circuits as part of the IC devices.

give the examples of sequential access memory?
