It MAY mean the latter but there are cases where it means the former but this is not clearly enough specified. In addition to the reasons already given, NC pins datasheeh sometimes used to provide somewhere to attach guard traces to.

You may then ask, why not just connect them to something?

I understood few of your points and I will work datzsheet to understand the rest! Here’s another perhaps even more interesting example, the TOP which is both an example of pin duplication, and of the [rare] pin removal dtaasheet the DIP package[s].

Between its D pin and everything else you [periodically] have hundreds of volts of rectified mains voltage. Ian Mason 91 3. You might ask then, why would anybody buy the part with more outputs than less if it’s the same die?

Removing the pins or designing a package with a custom number of pins would be very costly in terms of set-up. Post as a guest Name. There are of course different datasheer in which one such IC can be sold.


D0466bc haven’t reviewed the dies or anything, but I am absolutely convinced that some devices of the same class in the same package have the same silicon layout with different wire bonding to selectively disable features, allowing more effective price discrimination for a smaller number of silicon layouts.

There will be a part that has 4, 6, 8 outputs of something, but are all offered in similar if not the same package, probably even the same pinout. Re 2, I was going to say that, but then I realised that if the end-user leaves them NC or grounds them, or etc. Post Your Answer Discard By clicking “Post Your Answer”, you acknowledge that you have d4066hc our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies.

Datashret large packages you can have many spare pins. So that’s one alternative for “NC”. The reason comes out to be what the manufacturer of the chip guarantees and tests. The next larger standard package is used, resulting in unused pins.

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”. NC in this case meaning Not internally Connected. The datasheet even lists this among its features: Ajith Kumar 2 The chip manufacturers packaging 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. In addition to the other good reasons listed, I know that NC pins are sometimes also used when: By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies.


Some manufacturers will place NC pins beside inputs that might need a guard – Analog and Linear both do this on some of their low bias current Op-Amps. Here’s one that might be a bit less known: Also remember that price is directly proportional to feature set.

d4066c This could easily result in multiple adjacent NC pins since the larger package may have many extra pins. Not all parts or manufacturers do this, but it is definitely something that happens. A 6-output part could very well work the same as an 8-output part with dataaheet 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.
