Les deux circuits offrent des vitesses de transfert de donn\u00e9es typiques de 5 Mbits\/s (TLP2312) et 20 Mbits\/s (TLP2372) et sont sp\u00e9cialement con\u00e7us pour fonctionner avec des rails basse-tension, \u00e0 partir de 2,2 V. Cela leur permet de travailler avec les tensions tr\u00e8s basses utilis\u00e9es par de nombreux circuits p\u00e9riph\u00e9riques, notamment ceux en technologie LVCMOS (Low Voltage CMOS, ou CMOS basse-tension) 2,5 V, et aussi de s’accommoder de tensions jusqu\u2019\u00e0 5,5 V. Cette approche \u00e9vite le recours \u00e0 un rail d’alimentation s\u00e9par\u00e9 pour alimenter les photo-coupleurs, ce qui r\u00e9duit le nombre de composants et permet de gagner de la place.<\/p>\n

Avec un faible seuil de courant d’entr\u00e9e de 1,6 mA (maximum), et un courant d’alimentation bas de 0,5 mA (maximum) sur toute leur plage de temp\u00e9rature allant de -40\u00b0C \u00e0 +125\u00b0C, ces photo-coupleurs sont pilotables directement par des micro-contr\u00f4leurs, ce qui r\u00e9duit la consommation. Les deux dispositifs offrent une tension d’isolement de 3,75 kVeff pour un isolement s\u00fbr. Ils sont encapsul\u00e9s en bo\u00eetier SO6 \u00e0 5 broches de 2,3 mm d\u2019\u00e9paisseur maximale, offrant ainsi un profil bas pour les applications o\u00f9 la hauteur est limit\u00e9e, tout en apportant plus de libert\u00e9 pour l\u2019implantation des circuits imprim\u00e9s.<\/p>\n
