List of 7400 series integrated circuits

 * – (View AfD) (View log)

This is a fairly indiscriminate list of digital integrated circuits which happen to have "74" in their part numbers. Wikipedia is not a parts catalog. Wtshymanski (talk) 00:59, 16 September 2009 (UTC)
 * Keep - I don't know much about this topic, however this 7400 series seems like a pretty significant part of computer chip history. Its nothing I have any interest in but for someone who is interested in a topic like computer engineering, micro engineering or like studies this is may be a fascinating subject. I know I will be challanged for this next comment but according to Wikipedia article traffic data this article is visited by about 200-300 ips a day. My honest opinion is keep - Marcusmax  ( speak ) 02:45, 16 September 2009 (UTC)
 * For anyone interested in it, there is a topic on the series already at 7400 series.  TJ   Spyke   04:04, 16 September 2009 (UTC)
 * Comment the nominator appears to be misrepresenting the list. There is an *article* on the 7400 series - 7400 series - so this is not a random collection. 76.66.196.139 (talk) 04:00, 16 September 2009 (UTC)
 * Response to comment the article 7400 series is about the small-scale TTL integrated circuits. However the list as its stands now is a random collection of TTL, CMOS,HCMOS, and whatever. The talk page even discusses adding some programmable logic. There's no unity, and 5 minutes with a TI databook shows many omissions in the list. One might as well make a list from the Mc Master Carr catalog of nuts and bolts. --Wtshymanski (talk) 14:22, 16 September 2009 (UTC)
 * Keep - Did you read the entire 7400 series article? CMOS, HCMOS, etc. are listed under 7400 series derivative families.  The 74* numbering remains standard for the pin-compatible (usually) part #s, with additional indicators for logic family and, as mentioned under the part numbering scheme section.  Practically all the listed parts are made in multiple logic families, and are still manufactured (There's a number of companies in Russia that make them in the older logic families for use in legacy devices).  This stuff was covered extensively in the digital logic classes I took in college (SIAST, Computer Engineering Technology program) just last year, so it is very much still relevant.  Also, omissions are a reason to expand, not delete.  Grandmartin11 (talk) 17:41, 16 September 2009 (UTC)
 * Response to response your response only lists cleanup issues. If they are not part of the 7400 series as outlined in the introduction as to what the contents of the list should be, they can simply be removed. If the list is incomplete, tag it with a listdev. 76.66.196.139 (talk) 05:16, 17 September 2009 (UTC)
 * More on cleanup - so what do we keep? All the chips that were in the Texas Instruments TTL Handbook as of 1973 or ? And why? I've never understood the purpose of this list - a 2009 surface-mount HCMOS 3.3 volt 8-wide bilateral bus driver has nothing to do with a 1979 era 7400 quad 2-input NAND  bipolar full-power 5 volt part, their only association is that they are both "digital ICs" and hapen to share a "74" somewhere in the part number. And a list of function names and part numbers to me seems of low utilty - if you actually want design information, you need pinouts and specifications, which is properly the subject of manufactuer's data sheets,not a "general" encyclopedia. --Wtshymanski (talk) 13:27, 17 September 2009 (UTC)


 * Delete Random list of cruft, I can't think of anyone who would be interested in this.  TJ   Spyke   04:04, 16 September 2009 (UTC)
 * Keep, but... I see two points worth following up in the comments of those who wish to delete the list:
 * the question of what the list should not try to do is important; I think those (like myself) who actually find the list useful have a feeling for what should and should not be in it, but perhaps it should be codified somehow. I particularly think it must not try to be a selection guide (but could link to such things), but should list the basenumbers of what is not some "random" list of ICs (it should not include a uA741 for an obvious example!).
 * the usefulness of the list might be improved by arranging the devices by type (since a simple browser search can find a device by number), and I gave an example of such a table in the discussion page for the list. But I admit that such tables make less sense for devices other than gates. One of the valuable uses of the list, compared with an online supplier's catalog, which I'd still use when appropriate) is that the whole range of devices, old and new, is listed in one place and it is easy to find what I want by looking or searching - that cannot be said to be true with google searches (finds lots of junk) or looking at old thick manufacturers' manuals (probably miss some devices, and physically difficult to search - especially if you have to trot off to a library and look through several manuals).  Besides, the purpose of Wiki, surely, is to provide online encyclopaedic content. A really good encyclopaedia should mention these historically-important, widely-used chips but (of course) not try to list every manufacturer's list of capacitors, IC sockets or that sort of thing!


 * So I think the page should be kept, it certainly could be tidied or slightly reorganised, which would be helped by discussion from those who value the page... and some writing down of what it should and should not do. I do not think a page should be deleted because some people don't see why others find it useful.Maitchy (talk) 01:09, 19 September 2009 (UTC)


 * Keep looks like a notable addition to the main 7400 series article. Gives a detailed view of what this very important chip family in fact contains. Both historical and practical importance, analogous to the List of AMD Athlon 64 microprocessors and similar others. --Pot (talk) 11:59, 16 September 2009 (UTC)
 * Keep This is not a "Random list of cruft." The 7400 series are well known and used often in studying electrical engineering. I am interested in this list and it is different than the 7400 series article. In the field of electrical engineering, these parts are notable and there are some that are well known enough that people recognize the part by the number alone.Grizzlefuz (talk) 16:58, 16 September 2009 (UTC)
 * Keep It is a list of parts - however - it is of historical and practical importance.--Speedevil (talk) 17:03, 16 September 2009 (UTC)
 * Keep this is a wonderful reference, i am studying electrical engineering and refer to it     often, so for all the students out there, please keep --konan107 17:14 16 September 2009  —Preceding undated comment added 20:15, 16 September 2009 (UTC).
 * Strong keep The 7400 series was the first broadly accepted IC family and standardized digital logic for decades. The entire minicomputer era revolved around it. This list is almost as significant to the history of electronics as List of works by William Shakespeare is to English literature. Any problems with the current list should be fixed, of course, and I'd like to see date of introduction added, preferably as a table, so one could see what were the original parts and how the family grew. (I remember when the '245 was introduced. It replaced two ICs used multiple times in bus circuits and was such a big win that supplies were rationed and shipments were hijacked and sold on the black market.) The article certainly belongs here. --agr (talk) 21:54, 16 September 2009 (UTC)
 * Strong Keep. The 74-series logic has been around since the early 1970s, and as pointed out above, the entire minicomputer era revolved around it.  And until much later ( when FPGA's came along ) they were still used for simple logic in low-volume peripheral devices where an ASIC wouldnt be cost-effective.  They are still used by prototypers, hobbyists, and students, and AFAIK they are still sold at every Radio Shack. Squidfryerchef (talk) 14:40, 19 September 2009 (UTC)
 * Keep Not, as the nominator describes it, an "indiscriminate list of digital integrated circuits which happen to have "74" in their part numbers". The article lists members of the 7400 series, not simply ICs with "74" in their part number. Adambro (talk) 16:02, 19 September 2009 (UTC)
