But the data-sheet is not yet standardized by an Icecat editor. Product name is a key part of the Icecat product title on a product data-sheet. We map away wrong codes or sometimes logistic variants.

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.

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

So, I used an inverting bus tranceiver 74HCT to connect it to the rest of the system. Offhand, I’d say you made the right choice! JPG You do not have the required permissions to view the files attached to this post. A manufacturer can have multiple brand names. 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 74hcct640 you want right now.


Here’s what I get from page 10 of the http: The general trademark of a manufacturer by which the consumer knows its products. Actually though, unless you know 74hcg640 sure that all the other bits in CRA are 0 and datxsheet 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.

Embed the product datasheet into your content. The brand’s unique identifier for a product. Google [Bot] and 0 guests. I’m ready for another byte. Imagine that this responsive data-sheet is included in the product page of your webshop.

You can give it a lot more to make your address decoding hardware simpler and just not use more than four. dataasheet

Sorry, this information is not published yet! 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.


I remember that the little proto-board project that I did with the about 27 years ago! Page 2 of 2.

74HCT640 SOP20

Tue Jan 15, 5: Since the PIA has two and I think the is the same thingthat makes for four addresses. I found a datasheet at http: So going off this example: I like how you fixed it in software! 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.

The have these also, and I have only used them for other things. Tue Dec 11, 8: Previous topic Next topic.
