Any one please tell me definitions of TTL Logic Family,Emitter Coupled Logic,CMOS Logic Family,MOS Logic ICs?

TTL family is transistor transistor logic\nEmitter coupled logic is the fastest among this family,while it consumes the most power.\nCMOS expands to Complimentary Metal-Oxide-Semiconductor.It is most power efficient and hence is the most widely used logic family.\nFor an excellent introduction to the logic gate families read the reference

This site has a wealth of information. I often use it as a starting point when looking for a new type of circuit:\nhttp://www.discovercircuits.com/list.htm

AND gate: if both the inputs are on then output is on.If even one of the inputs is off then output is off\n\nNOT gate: if input is on then output is off and vice versa.\n\nOR gate: If even one of the inputs is on then output is on.If both are off then output is off.If both inputs are on then output is on.

Each hardware has its own software interface and supported protocol(s). You have to read manufacturer's documentation.

This depends on the logic family employed. For "standard CMOS" which is common today, +5V is 1 and 0V or ground is 0. However, other systems use other voltages. Lower voltages are common today for a few reasons. 3.3V logic, for example, is widely used where 3.3V is a 1 (and 0V is 0). However, it is possible to have negative logic. In addition, some high speed systems like ECL use voltages like -1.75V for a 0 and -0.9V for a 1 (this allows transistors to stay out of saturation which makes for fast switching but poor noise immunity and difficult design).

and or and not are logical functions but moreover they are gates not switches. Microcontrollers are made of thousands of transistors (sometimes referred to as switches.) as they are configured to create logical units and buffers. \n\nHowever to correct the author of the question, it is not a matter of switch type (transistor, such as HMOS, CMOS, NMOS for example) But more than that, one kind of switch could you not use to create a "CPU" and the answer to that is it depends on how slow  or fast it has to be. We could create one made up of Bi-polar Transistors it would be huge and very hot in comparison , however it can be done and has been. How do you think we got them to size and speed they are today..

The above answer is right but missing a detail (the carry bit if you need it).\n\nHS = X (XOR) Y\nCO = X (AND) Y\n\nwhere:\nHS => "half sum"\nCO => "carry out"\nX => input\nY => input\n\nNow, it seems you actually want to implement XOR and AND with discrete components (resistors, diodes, transistors)?  I would highly recommend buying packages rather than building them yourself.  You can get several gates on one small dual inline package that fits nicely on your breadboard or whatever.\n\nIf you really need to implement them with discrete components, I'm sure there are diagrams on the web showing XOR/AND gates for TTL and CMOS logic.

Short for complementary metal oxide semiconductor. Pronounced see-moss, CMOS is a widely used type of semiconductor. CMOS semiconductors use both NMOS (negative polarity) and PMOS (positive polarity) circuits. Since only one of the circuit types is on at any given time, CMOS chips require less power than chips using just one type of transistor. This makes them particularly attractive for use in battery-powered devices, such as portable computers. Personal computers also contain a small amount of battery-powered CMOS memory to hold the date, time, and system setup parameters.\n\nYes

As much as i know, all IC's have certain numbers. There are many many IC's that are performing many many different jobs. so in order to recongize which IC is doing what job it has a different number than a IC doing a different job. For example a IC used in a radio can not do the job of a IC used in TV and similarly a IC used in TV cannot do the job for a IC in radio. hence they have different numbers . so if a IC is damagerd it can only be replced by another IC of the same number.\nfor example  \n 74LS xxx  is transistor transistor logic. so if you take a microscope and look into this kind of IC you will find a lot of transistors. \nand  74HCxxx  OR Cd40xxx  series of IC are MOSFET based and if you take a microscope and look deep into these series u will find alot of MOSFET's .\nthankyou/

Actually NAND and NOR are called the universal Gates..\nNAND and NOR logic gates are the two pillars of logic, in that all other types of Boolean logic gates (i.e., AND, OR, NOT, XOR, XNOR) can be created from a suitable network of just NAND or just NOR gate(s). They can be built from relays or transistors, or any other technology that can create an inverter and a two-input AND or OR gate. Hence the NAND and NOR gates are called the universal gates.\n\nFor more info on gates pls see:\nhttp://en.wikipedia.org/wiki/logic_gate...
