 25 Dec 2006 19:39 Simple Important Question |
|
|
|
i am in a great dilemma regarding the nomenclature of the digital IC's. For example, considering simple gate series, i.e. 74 series.
Why the series is 74XX and why not 87XX of 92XX series or so? What is the significance of the 74XX series??

| 74 was the name given to a 'Family' of IC's called TTL (Transistor Transistor Logic) It was a very popular series and many digital device constructed since the 1970's contained these devices

It's 100% dependent from the IC manufacturer...
What we do is to assign series of numbers for each one of the families of parts and then free numbers are later selected inside each family range...
