5400 series was mil spec[edit]

The 5400 logic series was the military spec equivalent of the 7400 series. This was common knowledge among digital designers in the 1970's and 1980's. Constant314 (talk) 22:21, 23 April 2012 (UTC)

Pls give a reference for the common knowledge. Polmandc (talk) 04:50, 24 April 2012 (UTC)
Please refer to this link http://faculty.weber.edu/fonbrown/EE1000/Chapter%206.pdf

"The industry standard for logic device nomenclature today is the 5400/7400 series (originally developed by Texas Instruments); it is by far the most common and encompasses a great many logic families. The difference between the 5400 and the 7400 series is that the 5400 series devices operate over the military temperature range of -55°C to 125°C, and the less expensive 7400 series devices need only operate over the commercial temperature range of 0°C to 70°C."

This is only "common knowledge" among experienced and aged engineers, and this is rarely documented since military documentations generally will not be released to public. All the mil-spec that leaked out in the market is actually illegal stuffs except there are very common.

To make the discussion more complete, temperature range for IC can be divided into following categories: Commerical: 0-70C Industrial: -40-85C Automotive Grade: -40-125C (there are sub-grades but I think it is not important to mention) Military Grade: -55-125C

You can see there is a gradual trend of increase in temperature range. Rimsky.cheng (talk) 02:01, 3 October 2014 (UTC)

Comments on the article[edit]

1. The "Geophysical Service Incorporated" section overlaps with the text right under "History". I think "History" should focus on an overview. For consistency with the next two sections, "Geophysical Service Incorporated" should be renamed as “Seismic exploration” to reflect the main business of the company until l951.

2. "In 1956 TI began research on infrared technology that led to several line scanner contracts and with the addition of a second scan mirror the invention of the first forward looking infrared (FLIR) in 1963 with production beginning in 1966."

The sentence needs revision.

3. "The first single-chip gallium arsenide radar module was developed."

This is a sentence that does not provide a year and it looks like it's dangling in the paragraph.

4. "Adcock later became the first TI Principal Fellow."

I don't think this kind of information is particularly pertinent to this article.

5. This article says "The 7400 series of transistor-transistor logic (TTL) chips, developed by Texas Instruments in the 1960s". The TTL article says "TTL was invented in 1961 by James L. Buie of TRW". I see a contradiction.

6. " It discontinued the TI-99/4A (1981), the sequel to the 99/4, in late 1983 amidst an intense price war waged primarily against Commodore."

I'm not sure how I should interpret this sentence. If TI withdrew does it mean everybody was trying to compete with Commodore but nobody succeeded so TI pulled out of the competition?

7. The "described as" link in the "Artificial intelligence" section should be replaced by a note that points to a source at the bottom of the page.

8. The introduction talks about 2 divisions but the "Company divisions" section talks about 3. This is clearly a discrepancy that needs to be fixed. Also, if DLP is a division I don't understand why it should not have its own header instead of being under "Signal processing". Moreover, if the divisions should be listed and presented in the same sequence.

9. The Ducati multi-core processor line should have a simple description rather than a link going outside of Wikipedia.

10. If the "Microcontrollers and processors" lists a range of products I don't see why the other sections should do the same. Maybe the information that is listed is too much and it could go on a separate article.

11. “Notes” under “References” is empty and it could be removed.

12. Texas Instruments contributed to space exploration. It supplied resistors and transistors for the Saturn V for NASA's Apollo program: http://history.nasa.gov/SP-4206/app-e.htm. I think this should be mentioned.

13. The company has recently changed its logo. Look at how the dot on the i is rounded on the version which is linked on the Wikipedia page, and square on the company's website. [1] or just http://ti.com –- IMHO the article should be updated. — Preceding unsigned comment added by Bitvitez (talkcontribs) 23:46, 10 March 2016 (UTC)

Disposal of Sections and/or product lines[edit]

There is a section in this article that documents the acquisitions that Texas Instruments have made, but what about the opposite? T.I. used to make Numeric Display chips (e.g. TIL309) and probably LEDs, but not any more, unfortunately. Was this 'division' simply closed down, or was it sold to another company? Texas virtually invented the 74 TTL series, but appears to no longer do so. Again, was this closed down, or sold to someone else?
