===Other businesses===
TI's remaining businesses consisting of [[Digital Light Processing|DLP]] products (primarily used in projectors to create high-definition images), calculators and certain custom semiconductors known as application-specific integrated circuits.

Texas Instruments sells DLP technology for TVs, video projectors, and [[digital cinema]]. On February 2, 2000, Philippe Binant, technical manager of Digital Cinema Project at [[Gaumont (company)|Gaumont]] in France, realized the first digital cinema projection in Europe with the DLP Cinema technology developed by TI DLP technology enables a diverse range of display and advanced light control applications spanning industrial, enterprise, automotive, and consumer market segments.{{citation needed |date=July 2024|reason=Also ungrammatical, and no obvious reason to name this person.}}

;Custom application-specific integrated circuits (ASICs)

The ASICs business develops more complex integrated-circuit solutions for clients on a custom basis.

====Educational technology====
TI has produced educational toys for children, including the [[Little Professor]] in 1976 and [[Dataman]] in 1977.<ref>{{cite news|first1=James Floyd|last1=Kelly|access-date=2020-02-25|title=Super Bonus GeekDad Retro Gaming: DataMan|url=https://www.wired.com/2011/07/super-bonus-geekdad-retro-gaming-dataman/|newspaper=Wired|date=5 July 2011|issn=1059-1028|via=www.wired.com}}</ref><ref>{{cite web|first1=Benj|last1=Edwards|access-date=2020-02-25|title=The Golden Age of Texas Instruments Consumer Gadgets|url=https://uk.pcmag.com/electronics/86393/the-golden-age-of-texas-instruments-consumer-gadgets|date=1 December 2016|website=PCMag UK}}</ref>

TI produces a range of calculators, with the [[TI-30]] being one of the most popular early [[calculator]]s. TI has also developed a line of [[graphing calculator]]s, the first being the [[TI-81]], and most popular being the [[TI-83 Plus]] (with the [[TI-84 Plus]] being an updated equivalent).

Many TI calculators are still sold without graphing capabilities.<ref>{{Cite web|title=Education Technology &#124; Graphing Calculators &#124; Texas Instruments|url=https://education.ti.com/en|access-date=2022-09-23|website=education.ti.com|language=en}}</ref> The TI-30 has been replaced by the [[TI-30|TI-30X IIS]]. Also, some financial calculators are for sale on the TI website.

In 2007, TI released the [[TI-Nspire]] family of calculators and computer software that has similar capabilities to the calculators.

Less than 3% of Texas Instruments’ overall revenue comes from calculators, part of the $1.43 billion revenue in the "Other" section in the company's 2018 annual report. Nevertheless, the calculators are a lucrative product. For example, estimates have a $15 to $20 cost to produce TI-84 Plus which likely has a profit margin of at least 50%.

Throughout the 1980s, Texas Instruments worked closely with National Council of Teachers of Mathematics (NCTM) to develop a calculator to become the educational standard. In 1986, Connecticut School Board became the first to require a graphing calculator on state-mandated exams. Chicago Public Schools gave a free calculator to every student, beginning in the fourth grade, in 1988. New York required the calculator in 1992 for its Regents exams after first allowing it the previous year. The College Board  required calculators on the Advanced Placement tests in 1993 and allowed calculators on the SAT a year later. Texas Instruments provides free services to the College Board, which administers AP tests and the SAT, and also has a group called Teachers Teaching for Technology (T3), which educates teachers on how to use its calculators.<ref name="TIcalcsMedium" />

====TI calculator community====
In the 1990s, with the advent of TI's graphing calculator series, programming became popular among some students. The TI-8x series of calculators (beginning with the TI-81) came with a built-in [[TI-BASIC|BASIC]] interpreter, through which simple programs could be created. The TI-83 was the first in the series to receive native assembly.<ref>{{cite book|url=https://books.google.com/books?id=t-9dDwAAQBAJ&pg=PT33|title=Stand Out of Our Light: Freedom and Resistance in the Attention Economy|last=Williams|first=James Wilson|author-link=James Wilson Williams|publisher=[[Cambridge University Press]]|date=2018|access-date=2022-03-13|page=17|isbn=978-1-108-42909-2|doi=10.1017/9781108453004}}</ref> Around the same time that these programs were first being written, programmers began creating websites to host their work, along with tutorials and other calculator-relevant information. This led to the formation of TI calculator [[webrings]] and eventually a few large communities, including ticalc.org.<ref>{{Cite web|title=Welcome - ticalc.org|url=https://www.ticalc.org/|access-date=2022-09-23|website=www.ticalc.org}}</ref><ref>{{cite web|url=https://www.nytimes.com/library/tech/99/09/circuits/articles/02calc.html|title=Powerful Calculators Throw Teachers a New Curve|last=Lee|first=Jennifer|work=[[The New York Times]]|date=1999-09-02|access-date=2022-03-13|archive-url=https://web.archive.org/web/20220312225241/https://archive.nytimes.com/www.nytimes.com/library/tech/99/09/circuits/articles/02calc.html|archive-date=2022-03-12|url-status=live}}</ref><ref name=root.cz>{{cite web|url=https://www.root.cz/clanky/programovaci-jazyky-z-vyvojarskeho-pekla-spagetovy-kod-na-kalkulackach/|title=Programovací jazyky z vývojářského pekla: špagetový kód na kalkulačkách|language=cs|trans-title=Programming languages from development hell: spaghetti code on calculators|last=Tišnovský|first=Pavel|work=Root.cz|date=2016-06-14|access-date=2022-03-13|archive-url=https://web.archive.org/web/20220313001454/https://www.root.cz/clanky/programovaci-jazyky-z-vyvojarskeho-pekla-spagetovy-kod-na-kalkulackach/|archive-date=2022-03-13|url-status=live}}</ref>

The TI community reached the height of its popularity in the early 2000s, with many new websites and programming groups being started. In fact, the aforementioned community sites were exploding with activity, with close to 100 programs being uploaded daily by users of the sites. Also, a competition existed between both sites to be the top site in the community, which helped increase interest and activity in the community.

One of the common unifying forces that has united the community over the years has been the rather contentious relationship with TI regarding control over its graphing calculators.{{citation needed|date=March 2022}} TI graphing calculators generally fall into two distinct groups—the older ones powered by the [[Zilog Z80]] and the newer ones running on the [[Motorola 68000]] series.<ref name=root.cz/> Both lines of calculators are locked by TI with checks in the hardware and through the signing of software to disable use of custom operating systems. However, users discovered the keys and published them in 2009. TI responded by sending invalid [[DMCA]] [[takedown notice]]s, causing the [[Texas Instruments signing key controversy]].<ref>{{cite web|url=https://www.bizjournals.com/dallas/stories/2009/10/26/story6.html|url-access=limited|title=Hobbyists tangle with TI|last=Bounds|first=Jeff|work=[[Dallas Business Journal]]|date=2009-10-24|access-date=2022-03-13|archive-url=https://web.archive.org/web/20220313002427/https://www.bizjournals.com/dallas/stories/2009/10/26/story6.html|archive-date=2022-03-13|url-status=live}}</ref>
