♠ Inkcazo yeMveliso
Izixhobo ze-ISO774x zisebenza ngokuphezulu, i-quadchannel isolators yedijithali kunye ne-5000 VRMS (iphakheji ye-DW) kunye ne-3000 VRMS (iphakheji ye-DBQ yephakheji) ye-isolation ratings nge-UL 1577. Le ntsapho ibandakanya izixhobo ezinokulinganisa okuqinisiweyo kwe-insulation ngokwe-VDE, i-CSA, i-TUV kunye ne-CQC. Isixhobo se-ISO7741B senzelwe usetyenziso olufuna umlinganiselo wokugquma osisiseko kuphela.
Izixhobo ze-ISO774x zibonelela nge-immunity ephezulu ye-electromagnetic kunye nokukhutshwa okuphantsi kusetyenziso lwamandla aphantsi, ngelixa zikwahlula i-CMOS okanye i-LVCMOS digital I/Os. Ijelo ngalinye lokuzihlukanisa linoluvo lwe-logic kunye ne-output buffer eyahlulwe yi-silicon dioxide ephindwe kabini ye-capacitive (SiO2 ) umqobo wokugquma. Ezi zixhobo ziza nezikhonkwane ezinokuthi zisetyenziswe ukubeka iziphumo ezifanelekileyo kwi-impedance ephezulu yezicelo zokuqhuba iinkosi ezininzi kunye nokunciphisa ukusetyenziswa kwamandla. Isixhobo se-ISO7740 sinazo zonke iitshaneli ezine kwicala elinye, isixhobo se-ISO7741 sinemijelo emithathu eya phambili kunye neyokubuyela umva, kwaye isixhobo se-ISO7742 sineendlela ezimbini zokuya phambili nezimbini zokubuyela umva. Ukuba igalelo lamandla okanye umqondiso ulahlekile, imveliso engagqibekanga iphezulu kwizixhobo ezingenaso isimamva F kwaye iphantsi kwizixhobo ezinesimamva F. Bona icandelo Iindlela eziSebenzayo zeSixhobo ngeenkcukacha ezithe vetshe.
