EVOLUTION OF DIGITAL LOGIC FAMILIES In today's fast paced world, where everything is available just at a click on our mobiles or Laptops might seem like a Magic... But, How do these little wonders work??? What makes them operate so fast??? Might be among the few questions coming to your mind .... So basically if we give an insight into all these gadgets,it comprises of electronic components placed on one small flat piece of semiconductor that is normally silicon,these are called as Integrated Circuits(IC) .These components are place in orderly manner so as to function properly. IC's are made up of logic circuits.Logic circuits came from different logic families.So in a digital system if all the required IC's belong to a particular logic family then there is no problem of compatibility.But if different logic families are brought together then it becomes necessary to ensure compatibility,so for this we must understand different kinds of logic families and
