The chip manufacturers d4066gc factory may only support a few different packages, so there may not be one available with the correct number of pins, so you go up a size.

You might have different versions of the same series part. There’s no economic incentive to cut them out. What do you mean by “in stead of being just closed”, i. On some small fine pitch packages it’s difficult to get PCB traces between the pins to provide guard rings as required on very high impedance, low current inputs.

Some ICs have even NC continuously in accordance to their pin number.

D4066BC, D4066C, D4066G

Email Required, but never shown. The next larger standard package is used, resulting in unused pins. I understood few of your points and I will work on to understand the rest! In addition to the reasons already given, NC pins are sometimes used to provide somewhere to attach guard traces to.

The die will not fit into a package with the appropriate number of pins. Oct 13 ’15 at There are probably many more, but my fingers are tired. The duplication is again done for the same reasons mentioned before.

In case they have no use to the end users and have no function, why are they given as pins instead of being just closed? A 6-output part could very well work the same as an 8-output part with the 2 NCs being in reality 2 outputs, but if the manufacturer doesn’t stand by and guarantee those “NC outputs”, then nobody will realistically ever use it in products intended to be sold to the market.

Home Questions Tags Users Unanswered. Here’s one that might be a bit less known: Between its D pin and everything else you [periodically] have hundreds of volts of rectified mains voltage. It MAY mean the latter but there are cases where it means the former but this is not clearly enough specified.

What is a “closed terminal”? Ian Mason 91 3. It’s unclear what the alternative being proposed here is, but say an IC wants to sell in DIP8 format, but only needs pins, some will remain “NC”.

Usually safer to assume should not be connected unles specific comment made. The pin removal between C and D is to increase safety by maximizing distance creepage and clearance.

There are of course different packages in which one such IC can d4066bbc sold. This an SMPS controller with integrated main switch. NC in this case meaning Not internally Connected. Not having a physical pin?

Selling DBC, DC, DG with DBC, DC, DG Datasheet PDF of these parts.

Also remember that price is directly proportional to feature set. There will be a part that has 4, 6, 8 outputs of something, but are all offered daatasheet similar if not the same package, probably even the same pinout.

Re 2, Dataaheet was going to say that, but then I realised that if the end-user leaves them NC or grounds them, or etc. Sign up using Email and Password. Sign up using Facebook.

It also means an increase in silicon size if you have to add the additional bond pads to the die.

You might ask then, why would anybody buy the part with more outputs than less if it’s the same die?
