♠ ISO722x Dual-Channel Digital Isolators
Lisebelisoa tsa lelapa tsa ISO7220x le ISO7221x ke li-isolators tsa dijithale tse peli. Ho nolofatsa sebopeho sa PCB, likanale li lebisitsoe nqa e le 'ngoe ho ISO7220x le mahlakoreng a fapaneng ho ISO7221x. Lisebelisoa tsena li na le "logic input input and output buffer" e arohaneng le TI's silicon-dioxide (SiO2) isolation barrier, e fana ka karohano ea galvanic ea ho fihla ho 4000 VPK ka VDE. Li sebelisoa hammoho le lisebelisoa tsa motlakase tse ka thōko, lisebelisoa tsena li thibela maqhubu a phahameng a motlakase le libaka tse arohaneng, hammoho le ho thibela maqhubu a lerata a beseng ea data kapa lipotolohong tse ling ho kena mobung oa sebaka seo le ho kena-kenana le kapa ho senya li-circuits tse hlokolosi.
