I found a datasheet at http: Please, try again later. We map away wrong codes or sometimes logistic variants. Speaking of vagaries of VIA usage, this computer my KimKlone has opcodes that talk to one of a VIA’s bit counters, rendering it part of the programming model.

That doesn’t mean you have to give it only four addresses. JPG You do not have the required permissions to view the files attached to this post. Page 2 of 2. Some manufacturers license their brand names to other producers. Product name is a brand’s identification of a product, often a model name, but not totally unique as it can include some product variants.

Sacramento, CA, United States. Sorry, this information is not published yet! I dug it out and had my co-worker take a picture of its long-dead corpse. Actually though, unless you know for sure that all the other bits in CRA are 0 and you want to keep them that way, it would be better to use an instruction or sequence of instructions that sets only that bit and leaves the rest unaffected.

The have these also, and I have only used them for other things. Tue Dec 11, 8: Since the PIA has two and I think the is the same thingthat makes for four addresses.

Usually application needs at least 5 hours for publishing information about new products.

You can give it a lot more to make your address decoding hardware simpler and just not use more than four. Add to compare Don’t compare Add to compare You can only compare products that are fully described in the Icecat standard format, and datassheet to the same category.

I like how you fixed it in software! Tue Dec 31, 2: It’s generally two to the power of however many register-select inputs there are. Imagine that this responsive data-sheet is included in the product page of your webshop. Thanks for looking that up for me, Garth. Tue Jan 15, 5: Mon Dec 31, 2: Users browsing this forum: If you do give it more, the four you need will get reflected in other addresses; but if you don’t use them, it does not cause any problems. If datasheer continue to use this site we will assume that you are happy with it.

Multiple product codes can be mapped to one mother product data-sheet if the specifications are identical. Sat Aug 03, I remember that the dagasheet proto-board project that I did with dataxheet about 27 years ago!

74HCT640 Datasheet

An alternative 74gct640 — besides a jumble of jumpers on top of jumpers — would be to redefine the pinout by turning the chip upside down, and then bending the pins around or soldering to some sort of adapter. The brand’s unique identifier for a product.

Offhand, I’d say you made the right choice!

Category Does not fit in any category. The general trademark of a manufacturer by which the consumer knows its products. Login or signup for Full Icecat to access all product specs. So, I used daatasheet inverting bus tranceiver 74HCT 74uct640 connect it to the rest of the system. Bit 0 ie, the bit whose value is 1, the number you put in your first line has to do with enabling interrupts caused by an active edge on CA1; so that’s not what you want right now.

Google [Bot] and 0 guests. Cool — so you have d0 on one IC connected to d7 on the other, d1 to d6and so on?

Embed the product datasheet into your content. The idea for use like on a parallel printer, where you write to the port for example, one line tells the printer, “I have new data for you,” and the printer takes it and uses the other line to say, “Thanks. So going off this example:
