I can find the datasheet for CDB types and CD types but they don’t seem datasheeet reference each other. Many manufacturers make the same ICs. What is the difference between these – is it a silicon revision or do they have different functionality?

If the manufacture you are using doesn’t provide a datasheet to you, then you shouldn’t be using them.

The suffix letter, according to wikipedia, will tell you about the output buffer. I can’t find any non -B IC’s.

At least that’s what the manufacturers’ websites tell me. Today, only the B versions of the logic ICs seem to be available.

The output and, actually, input The buffered outputs are able to source or sink more current than the unbuffered outputs, thus eliminating the need for discrete switching transistors in some designs.

I have actually told my students this a few times. Sign up using Facebook. To be sure, you would need a data sheet that tells you the specifics about device marking code. The A series was unbuffered, while the B series featured buffered inputs and outputs in the form of additional, simple logic gates. Is there a manufacturer’s logo on the chip?

Further suffix letters 2nd, 3rd, I think it’s pretty safe to say that the CD number is the generic number, not caring about specific properties like buffered outputs, just the basic logic function. Have you checked the datasheet? Sign up using Email and Password.

What is the difference between a non-buffered IC and a buffered IC? It might be the case that some manufacturers produce the buffered version -Bbut mark the actual devices without the Cd4081.

Do you have a link for the without B series data sheet? Home Questions Tags Users Unanswered.
