I went through the TTL- and LS-family lists on TI's website and added all that weren't yet listed. --Arteitle 06:45, Oct 18, 2004 (UTC)

Keep out the CMOS parts

I'm not sure who would use this list but shouldn't it confine itself to actual bipolar 5-volt TTL parts, and not CMOS stuff like 744060, etc.? --Wtshymanski 22:16, 7 June 2006 (UTC)

I just removed a couple of 744??? entries and added a general comment about such 4000 series equivilents in the notes section. Plugwash 04:54, 26 November 2006 (UTC)

This article is, as the title suggests, a "list of 7400 series integrated circuits". Whether they happen to be TTL or CMOS is irrelevant; almost all recent 7400 series parts are CMOS or BiCMOS.

The article says "list of 7400 TTL integrated circuits" - so non-bipolar parts are inconsistent with this description. Might as well describe it as "List of ICs with "74" somewhere in the part number." This would not be encylopedia. --Wtshymanski 16:46, 20 January 2007 (UTC)

What wouldn't belong here would be 8000 and 8200 series TTL parts, and 4000/4500 series CMOS parts (though their 74xxx analogs are fine). --Brouhaha 21:25, 15 January 2007 (UTC)

Not encylopediac

Read WP:NOT and tell me why this article should be here - it's not very encyclopediac, is it? --Wtshymanski 18:42, 4 January 2007 (UTC)

On the contrary...

[[WP:NOT] states:

"Wikipedia is not a paper encyclopedia. This means that there is no practical limit to the number of topics we can cover, or the total amount of content..."

This list is useful to us engineers and very much Wikipediac. Rather than being deleted, this topic should be expanded with information about the different families (74LS, 74HC, 74HCT...) -- possibly in a related entry with links both ways.

If there is a specific part of WP:NOT that you believe applies, please specify it.

Guymacon 18:39, 15 January 2007 (UTC)

I agree with Guy Macon regarding the article being appropriate. AFAIK there is not a similary comprehensive list of 7400 series parts anywhere. Vendors only list their own parts, and drop long-obsolete parts from their lists.

I also agree with him about expanding the page to provide even more useful content. In fact, when I created this article from material originally in Talk:7400 series, it occurred to me that it would be nice to include for each part the specific families the part was made in, but I have not had time to compile that. I think it is important to keep each entry verifiable from databooks and datasheets, so I don't want to try to add that information from memory. --Brouhaha 21:30, 15 January 2007 (UTC)

The part of WP:NOT is that Wikipedia is not meant to be a directory. This is as bad as that long list of asteroid numbers that someone has created, or a list of Winnipeg bus stops by number...each entry is of negligable interest, and big dumb lists (especially with Wikipedia's grade of fact-checking)are not very encyclopediac. Anyone actually practicing engineering is *not* goign to use the Wikipedia as a source anyway. Anyone restoring old gear as a hobby will likely have better, more complete references around. Just knowing that a 74123 is a multivibrator is not going to give you a whole lot of useful information (like the pinout!). While Wikipedia is very large, it's not infinite and this article takes up more space than it's worth. --Wtshymanski 16:46, 20 January 2007 (UTC)

If you feel so strongly about it, AfD it. If you're aware of "better, more complete references", feel free to cite them. I've been in the industry for over 20 years and haven't seen any that qualify. There are some that are more complete on non-74xx parts, but the only lists of 74xx parts I've found elsewhere are less complete and not from authoritative sources. As discussed elsewere on this talk page, we've made a point of verifying and citing sources. --Brouhaha 23:24, 20 January 2007 (UTC)

Never ask a Legionaire about his past, or a Wikipedian for his references. If I'm looking up some old-timey mid '70s part I turn to the Texas Instruments "TTL Data Book for Design Engineers" - I have a couple of editions of this up to the mid '90s. If I'm looking for a current part number I'd hit the DigiKey catalog Web page. --Wtshymanski 17:02, 21 January 2007 (UTC)

OK so my references are the same as the article references. I still think the list is too specialized for a general reference encyclopedia. --Wtshymanski 17:23, 21 January 2007 (UTC)

Note: digchip.com triggered the Wikipedia spam filter, so I changed the http:// to ht REMOVE_THIS tp://

Added:

747266 Quad 2-input Exclusive-nor Gate

Phillips 74HC7266 datasheet:

http://www.ortodoxism.ro/datasheets/philips/74HC7266.pdf

74230 Octal Buffer/Driver with 3-state outputs

TI SN74AS230A datasheet:

http://www.unicornelectronics.com/ftp/Data%20Sheets/74as230.pdf

74222 16 x 4 Synchronous FIFO Memory with 3-State Outputs

I have a TI SN74LS222N (also listed as SN74LS222N) in my hand, but could not find a datasheet. It appears to be:

SN54LS222A 16 × 4 SYNCHRONOUS FIRST-IN, FIRST-OUT MEMORY WITH 3-STATE OUTPUTS

...but I can't be sure without a datasheet.

12.145.33.227 23:17, 18 January 2007 (UTC)

Do these count as 7400 series ICs?

Texas Instruments SN74AUP1G57 Low-Power Configurable Multiple-Function Gate

Texas Instruments SN74AUP1G58 Low-Power Configurable Multiple-Function Gate

Texas Instruments SN74LVC1G98 Configurable Multiple-Function Gate

Texas Instruments SN74LVC1G97 Configurable Multiple-Function Gate

Texas Instruments SN74LVC1G98 Configurable Multiple-Function Gate

Texas Instruments SN74LVC1G99 Ultra-Configurable Multi-Function Gate With 3-State Outputs

If so, what number should they be listed under? Numbers 74157-58 74197-99 are already used by other parts.

Guy Macon http://www.guymacon.com

12.145.33.227 01:47, 19 January 2007 (UTC)

I'd add a new section and list them as "1G57", etc., since AUP and LVC are the families. --Brouhaha 01:37, 20 January 2007 (UTC)

You see, if the list had any focus, we'd not have this problem. A list of "everything with 74 in it" is not encyclopediac. --Wtshymanski 16:46, 20 January 2007 (UTC)

This definitely is NOT a list of everything with 74 in it. For instance, an LM374, MC3474, uA741, MM5740, or CD4074 is obviously not a 7400-series logic part. If you don't have enough experience to distinguish 7400 series ICs from unrelated ICs with a 74 in the part number, we'll be happy to provide assistance. --Brouhaha 23:24, 20 January 2007 (UTC)

Tsk, tsk. A little personal, that. Don't forget the Wikipedia culture that asserts all editors are equally qualified. This list is unfocussed - some whiz-bang QFP bus interface thingy that's made of CMOS and runs on 3.3 volts has little similarity to a SN7400 running on 5 volts made of bipolar transistors. They are different technologies, not interoperable, different logic levels - all they might share is the SN74 somewhere in the part number. Who would use this list? And why would you use this list instead of an authoritative reference like, oh, say, the DigiKey catalog site or the Texas Instruments data books? Why isn't an LM741 included in this list? What are the criteria for membership in the list? This should be stated in the opening lines of the article. Big dumb lists need good justifications for their existence. --Wtshymanski 17:02, 21 January 2007 (UTC)

"the Wikipedia culture that asserts all editors are equally qualified." - sounds like complete BS to me. I'm not qualifed to edit an article on the Democratic Republic of Congo (to pick something completely at random), and freely admit it. There are assuredly some editors who are not qualified to edit a list of 7400 series integrated circuits. If you think there is a "7400 series" that includes the 741 opamp, by all means please add it to the list, along with a relevant reference. As far as a part like the 74LVC1G99 goes, it is clearly a 7400 series part, as the 74LVC family is a fairly recent variant of the 7400 series, and the 74LVC1G99 is clearly part of the 74LVC family. My suggestion of adding a new section was probably a bad idea; the real question is the lexicographic ordering of "G" relative to digits. --Brouhaha 01:24, 22 January 2007 (UTC)

Insofar as Wtshymanski's arguments are valid, they are arguments for improving this entry, not for deleting it, and are based on the incorrect assumption that "7400 series" has no meaning to an experienced electronics engineer other than "part number that has 74 in it." (I say "experienced" because recent grads may have never worked with 7400 series logic.)Guymacon 19:06, 22 January 2007 (UTC)

http://www.alldatasheet.com/ttl_list.html has a list of 7400 series parts.

Guymacon 19:11, 22 January 2007 (UTC)

a small fix

i changed the links to the non-existant article "Exclusive NOR" (which redirects to the article on logical equality) to point to the more relevant article "XNOR gate". 142.165.95.83 23:06, 31 January 2007 (UTC)
