Er erlaubt die bidirektionale Kommunikation \u00fcber die Levelgrenzen hinweg und das nicht nur f\u00fcr ein Signal, sondern gleich f\u00fcr vier. Dies erm\u00f6glicht es, ganze Schnittstellen wie I\u00b2C und UART oder andere Anwendungen auf unterschiedlichen Logikleveln zu realisieren.<\/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<figure class=\"wp-block-table\"><table id=\"wpls-table-1\"><tbody><tr><td><strong>Description<\/strong><\/td><td><strong>Worth<\/strong><\/td><\/tr><tr><td>Signal1 3,3V<\/td><td>LV1<\/td><\/tr><tr><td>Signal2 3,3V<\/td><td>LV2<\/td><\/tr><tr><td>Masse von 3,3V<\/td><td>Ground<\/td><\/tr><tr><td>Operating voltage 3.3V<\/td><td>LV<\/td><\/tr><tr><td>Signal3 3.3V<\/td><td>LV3<\/td><\/tr><tr><td>Signal4 3.3V<\/td><td>LV4<\/td><\/tr><tr><td>Signal1 5V<\/td><td>HV1<\/td><\/tr><tr><td>Signal2 5V<\/td><td>HV2<\/td><\/tr><tr><td>Masse von 5V<\/td><td>Ground<\/td><\/tr><tr><td>Betriebsspannung 5V<\/td><td>HV<\/td><\/tr><tr><td>Signal3 5V<\/td><td>HV3<\/td><\/tr><tr><td>Signal4 5V<\/td><td>HV4<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"anwendungsbereiche\"><span class=\"ez-toc-section\" id=\"Anwendungsbereiche\"><\/span>Areas of application<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Kommunikation zwischen 5V und 3V Microcontrollern<\/li>\n\n\n\n<li>Anschluss von 5V Sensoren an 3V Microcontrollern<\/li>\n\n\n\n<li>Anschluss von 3V Sensoren an 5V Microcontrollern<\/li>\n\n\n\n<li>\u2026<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"ansichten\"><span class=\"ez-toc-section\" id=\"Ansichten\"><\/span>Views<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-2 is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/www.fambach.net\/en\/logik-level-konverter\/logicconverterbottom\/\"><img loading=\"lazy\" decoding=\"async\" width=\"651\" height=\"559\" data-id=\"5397\" src=\"https:\/\/www.fambach.net\/wp-content\/uploads\/LogicConverterBottom.jpg\" alt=\"Logiklevelkonverter von unten\" class=\"wp-image-5397\" srcset=\"https:\/\/www.fambach.net\/wp-content\/uploads\/LogicConverterBottom.jpg 651w, https:\/\/www.fambach.net\/wp-content\/uploads\/LogicConverterBottom-300x258.jpg 300w, https:\/\/www.fambach.net\/wp-content\/uploads\/LogicConverterBottom-14x12.jpg 14w\" sizes=\"auto, (max-width: 599px) calc(100vw -
