I understood few of your points and I will work on to understand the rest! Ajith Kumar 2 Here’s one that might be a bit less known: Null 4, 10 22 Sign up using Email and Password. Also remember that price is directly proportional to feature set.

What happens is, the silicon datashwet the 4 output devices is the exact same as in an 8 output, except 4 pins are just labeled “NC” on the datasheet! Between its D pin and everything else you [periodically] have hundreds of volts of rectified mains voltage.

What do d4066hc mean by “in stead of being just closed”, i. Here’s another perhaps even more interesting example, the TOP which is both an example of pin duplication, and of the [rare] pin removal in the DIP package[s]. 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.

Furthermore, doing that would physically destabilize the package. Usually safer to assume should not be connected unles specific comment made. NC in this case meaning Not internally Connected. In addition to the reasons already given, NC pins are sometimes used to provide somewhere to attach guard traces to.

Some ICs have even NC continuously in accordance to their pin number. In addition to the other good reasons listed, I know that NC pins are sometimes also used when: The datasheet even lists this among its features: You might want an oversize package for thermal performance or size of dieand as a dattasheet you end up f4066bc a package with more pins than you need.

Though I suppose they wouldn’t list the pins as NC if that was a danger. You might ask then, why would anybody buy the part with more outputs than less if it’s the same die?

You’ll see in the image below that in some packages d466bc pins are used for d4066bbc given function duplicated to increase allowable current etc. I 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 datawheet discrimination for a smaller number of silicon layouts.

The pin removal between C and D is to increase safety by maximizing distance creepage and clearance. Not having a physical pin?

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. So if you need 4 pins, but there is a standard package with 5, you have one spare.

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. There may be performance related issues with bonding the extra pins stubs in high frequency circuits?

d4066c There are of course different packages in which one such IC can be sold. The reason comes out to be what the manufacturer of the chip guarantees and tests. There’s no economic incentive to cut them out.

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. The next larger standard package is used, resulting in unused pins. Post as a v4066bc Name. 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?
