Commercial integrated circuits appeared in 1961, and recently Texas Instruments published <a href=\"https:\/\/news.ti.com\/blog\/2021\/06\/24\/developing-first-ics-to-orbit-earth\" target=\"_blank\">a fascinating retrospective on the development of their first few digital ICs<\/a>.<\/p>\n<p>TI\u2019s original IC product on the market was the <a href=\"https:\/\/www.computerhistory.org\/collections\/catalog\/102762884\" target=\"_blank\">SN502<\/a>, a transistor flip-flop that debuted at $450 (about $4100 today), which caught the interest of NASA engineers who asked for logic functions with a higher performance level. The response was the development of the 51 series of logic chips, whose innovation included on-chip interconnects replacing the hand interconnects of the SN502. Their RCTL logic gave enough performance and reliability for NASA to use, and in late 1963 the <a href=\"https:\/\/en.wikipedia.org\/wiki\/Explorer_18\" target=\"_blank\">Explorer 18<\/a> craft carried a telemetry system using the SN510 and SN514 chips into orbit. 52 and 53 series chips quickly followed, then in 1964 the <a href=\"https:\/\/hackaday.com\/2018\/12\/28\/the-7400-quad-2-input-nand-gate-a-neglected-survivor-from-a-pre-microprocessor-world\/\">54 series TTL chips<\/a> which along with their plastic-encapsulated 74 series equivalents <a href=\"https:\/\/www.ti.com\/product\/SN5400\" target=\"_blank\">are still available today<\/a>.<\/p>\n<p>Considering that in 1961 the bleeding edge of integrated circuit logic technology was a two-transistor chip with hand interconnects, it seems scarcely conceivable that by ten years later in 1971 the art had advanced to the point at which <a href=\"https:\/\/hackaday.com\/2018\/01\/29\/inventing-the-microprocessor-the-intel-4004\/\">the first commercially available microprocessors would be produced<\/a>. It\u2019s unlikely that many of us will stumble upon any of the three-figure SN1-series logic chips, but to read about them is a fascinating reminder of this pivotal moment in the history of electronics.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Over six decades of integrated circuit production we\u2019ve become used to their extreme reliability and performance for a very reasonable price.
