Tue Dec 31, 2: Page 2 of 2. Please, try again later. You won’t find that on a data sheet! A manufacturer datadheet have multiple brand names.

The general trademark of a manufacturer by which the consumer knows its products. Sacramento, CA, United States. JPG You do not have the required permissions to view the files attached to this post. 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 soldering to some sort of adapter.

Imagine that this responsive data-sheet is included in the product page of your webshop.

74HCT640 – Octal Bus Transceiver, 3 State, TTL Logic Level

So going off this example: Tue Jan 15, 5: Thanks for looking that up for me, Garth. Mon Dec 31, 2: More Sharing Services Share.

I found a datasheet at http: Product name is a brand’s identification of a product, often a model name, but not totally unique as it can include some 74hct6640 variants. What type of chip would be good for an FDC. That doesn’t mean you have to give it only four addresses.

Users browsing this forum: The brand’s unique identifier for a product. Tue Dec 11, 8: I like how you fixed it in software!

Here’s what I get from page 10 of the http: If you do give it more, the four you need will get reflected in other addresses; but if you don’t use datashete, it does not cause any problems. We map away datasheet codes or sometimes logistic variants. 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 dstasheet only that bit and leaves the rest unaffected.

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

Add to compare Don’t compare Add to compare You can only compare products that are fully described in the Icecat standard format, and belong to the same category. Since the PIA has two and I think the is the same thingthat makes for four addresses. But the data-sheet is not yet standardized by an Icecat editor. Sorry, this information is not published yet! I remember that the little proto-board project that I did with the about 27 years ago!

Cool — so you have d0 on one IC connected to d7 on the other, d1 to d6and so on? The have these also, and I have only used them for other things. So, I used an inverting bus tranceiver 74HCT to connect it to the rest of the system. It’s generally two to the power of however many register-select inputs there are. I dug it out and had my co-worker take a picture of its long-dead corpse. Product name is a key part of the Icecat product title on a product data-sheet.

Embed the product datasheet into your content. Category Does not fit in any category. Sat Aug 03, You can give it a lot more to make your address decoding hardware simpler and just not use more than four. If you continue to use this site we will assume that you are happy with it. Google [Bot] and 0 guests. 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.

I’m ready for another byte. Moreover, I needed the counter to increment, not decrement– again, something you won’t find on the 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.

Multiple product codes can be mapped to one mother product data-sheet if the specifications are identical.

Bit 0 ie, the bit whose value is 1, the number you put in your first line has 74hct64 do with enabling interrupts caused by an active edge on CA1; so that’s not what you want right now. Offhand, I’d say you made the right choice! Some manufacturers license their brand names to other producers. Previous topic Next topic.
