Mit dem ersten IC der TTL Serie, k\u00f6nnen weitere Grundschaltungen erstellt werden, so dass man nur eine Art von IC br\u00e4uchte. Dies machte das IC so vielf\u00e4ltig und beliebt in seiner Zeit. Leider ist die Zeit der TTL Bausteine vor\u00fcber, heute werden mehr diese meist durch kleine Controller ersetzt, die mit Software programmiert, komplexe Logiken abbilden k\u00f6nnen. Dennoch leitet dieser Baustein auch meine TTL Serie ein. Die Verwendung der Bausteine dient dem besseren Grundverst\u00e4ndnis, was als Basis f\u00fcr komplexere Schaltungen oder auch f\u00fcr die Programmierung hilfreich ist. Auch ist nicht auszuschlie\u00dfen, dass solch ein Baustein einmal seine Anwendung mit einem Microcontroller findet, um beispielsweise weniger GPIOs zu ben\u00f6tigen. (Beispiel ODER Schaltung zweier Kollisions-Taster. Sobald einer gedr\u00fcckt ist, besteht eine Kollision, es wird aber nur ein GPIO ben\u00f6tigt (Ich wei\u00df geht auch ohne Baustein \ud83d\ude09 ).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><span class=\"ub-content-link ub-content-link--ok ub-content-link--status-after\"><a href=\"https:\/\/www.fambach.net\/en\/ttlerklaert\/\" data-type=\"post\" data-id=\"10909\" class=\"ub-content-link__anchor\">Was ist ein TTL IC?<\/a><span class=\"ub-status ub-status--ok\" title=\"Link status: OK\"><span class=\"ub-status__icon\" aria-hidden=\"true\">\u25cf<\/span><span class=\"screen-reader-text\">Link status: OK<\/span><\/span><\/span><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"fakten\"><span class=\"ez-toc-section\" id=\"Fakten\"><\/span>Facts<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"schaltzeichen-fuer-nand\"><span class=\"ez-toc-section\" id=\"Schaltzeichen_fur_NAND\"><\/span>NAND symbol<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"620\" height=\"110\" src=\"https:\/\/www.fambach.net\/wp-content\/uploads\/2024-06-01-14_08_41.jpg\" alt=\"\" class=\"wp-image-11074\" srcset=\"https:\/\/www.fambach.net\/wp-content\/uploads\/2024-06-01-14_08_41.jpg 620w, https:\/\/www.fambach.net\/wp-content\/uploads\/2024-06-01-14_08_41-300x53.jpg 300w, https:\/\/www.fambach.net\/wp-content\/uploads\/2024-06-01-14_08_41-18x3.jpg 18w\" sizes=\"auto, (max-width: 599px) calc(100vw -
