Descriptifs :<\/span><\/span><\/h6>\n

Le 74HC540\u00a0; <\/span>Le 74HCT540 est un pilote de tampon\/ligne inverseur 8 bits avec des sorties \u00e0 3 \u00e9tats. <\/span>L’appareil dispose de deux activations de sortie (OE1 et OE2). <\/span>Un niveau HIGH sur OEn am\u00e8ne les sorties \u00e0 adopter un \u00e9tat OFF \u00e0 haute imp\u00e9dance. <\/span>Les entr\u00e9es incluent des diodes \u00e0 pince. <\/span>Cela permet d’utiliser des r\u00e9sistances de limitation de courant pour interfacer les entr\u00e9es \u00e0 des tensions sup\u00e9rieures \u00e0 VCC.<\/span><\/span><\/p>\n
