♠ ISO7021 I-Ultra-Low Power ye-Ultra-Low-Channel yeDijithali ye-Digital
Isixhobo se-ISO7021 sinamandla asezantsi kakhulu, i-multichannel digital isolator enokusetyenziswa ukwahlula i-CMOS okanye i-LVCMOS digital I/Os.Ijelo ngalinye lokuzihlukanisa linegalelo lengqiqo kunye nesithinteli esiphumayo esahlulwe yi-silicon dioxide ephindwe kabini ye-capacitive (SiO2) umqobo wokugquma.Uyilo olusekwe kumda olutsha oludityaniswe ne-ON-OFF isikimu sokumodareyitha isitshixo sivumela aba babodwa ukuba basebenzise amandla aphantsi kakhulu ngelixa bedibana ne-3000-VRMS yokukala ukwahlula nge-UL1577 nganye.Ijelo ngalinye losetyenziso oluguquguqukayo lwangoku lwesixhobo lungaphantsi kwe-120 μA/Mbps kunye nejelo ngalinye losetyenziso olungatshintshiyo lwangoku luyi-4.8 μA kwi-3.3 V, evumela ukusetyenziswa kwe-ISO7021 kuwo omabini amandla kunye noyilo lwenkqubo yoxinzelelo lwe-thermal.
Isixhobo sinokusebenza ngaphantsi kwe-1.71 V, ukuya kuthi ga kwi-5.5 V, kwaye sisebenza ngokupheleleyo kunye nombane ohlukeneyo wokubonelela kwicala ngalinye lomqobo wokuzihlukanisa.I-isolator ye-two-channel iza kumzimba omxinwa we-8-SOIC iphakheji kunye nejelo elinye eliya phambili kunye nelinye elibuyela umva kwiphakheji ye-8-SOIC.Isixhobo sinokhetho olungagqibekanga oluphezulu noluphantsi.Ukuba igalelo lamandla okanye umqondiso ulahlekile, imveliso engagqibekanga iphezulu kwisixhobo se-ISO7021 ngaphandle kwesimamva F kwaye sisezantsi kwisixhobo se-ISO7021F kunye nesimamva sika-F.Jonga icandelo leeNdlela zokuSebenza kweSixhobo ngolwazi olungakumbi.
