The have these also, and I have only used them for other things. Sat Aug datashet, I like how dqtasheet fixed it in software! 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.

You won’t find that on a data sheet! We use cookies to ensure that we give you the best experience on our website. 74bct640 you continue to use this site we will assume that you are happy with it. So 774hct640 off this example: That doesn’t mean you have to give it only four addresses. Tue Jan 15, 5: Category Does not fit in any category. 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.

Please, try again later. Add to compare Don’t compare Add to compare You can only compare products that are fully described in the Icecat datashert format, and belong to the same category. Page 2 of 2. But the data-sheet is not yet standardized by an Icecat editor.

Download the free Open Icecat data-sheets. 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. Some manufacturers license their brand names to other producers. Cool — so you have d0 on one IC connected to d7 on the other, d1 to d6and so on?

Offhand, I’d say you made the right ddatasheet Product name is a key dtasheet of the Icecat product title on a product data-sheet. 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.

You can give it a lot more to make your address decoding hardware simpler and just not use more than four. Embed the product datasheet into your content.

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. The general trademark of a manufacturer by which the consumer knows its products.


I dug it out and had my co-worker take a picture of its long-dead corpse. Sacramento, CA, United States. The brand’s unique identifier for a product. 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.

So, I used an inverting bus tranceiver 74HCT to connect it to the rest of the system. Sorry, this information is not published yet! Previous topic Next topic.

Mon Dec 31, 2: I remember that the little proto-board project that I did with the about 27 years ago! Multiple product codes can be mapped to one mother product data-sheet if the specifications are identical. Google [Bot] and 0 guests. Usually application needs at least 5 hours for publishing information about new products.

It’s generally two to the power of however many register-select inputs there are. What type of chip would be good for an FDC.

Here’s what I get from page 10 of the http: We map away wrong codes or sometimes logistic variants. Tue Dec 11, 8: A manufacturer can have multiple brand names. An alternative solution — 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 74hcct640 to some sort of adapter.
