♠ I-ISO722x i-Dual-Channel Digital Isolators
I-ISO7220x kunye ne-ISO7221x izixhobo zosapho zi-dualchannel digital isolators. Ukuququzelela ubeko lwePCB, iitshaneli zilungelelaniswe kwicala elifanayo kwi-ISO7220x kwaye kumacala achaseneyo kwi-ISO7221x. Ezi zixhobo zine-logic input kunye ne-output buffer eyahlulwe yi-TI's silicon-dioxide (SiO2) isithintelo sokuzihlukanisa, ukubonelela ukuhlukaniswa kwegalvanic ukuya kwi-4000 VPK nge-VDE nganye. Zisetyenziswa ngokudityaniswa nonikezelo lwamandla oluzimeleyo, ezi zixhobo zivala amandla ombane aphezulu kunye neziseko ezizimeleyo, kunye nokuthintela imisinga yengxolo kwibhasi yedatha okanye ezinye iisekethe ekungeneni kumhlaba wendawo kwaye ziphazamise okanye zonakalise iisekhethi ezinovakalelo.
Uphawu lwe-binary input lubekwe kwimeko, luguqulelwe kwisignali elinganayo, emva koko yahlulwe ngumqobo wokuhlukanisa i-capacitive. Ngaphaya komqobo wokuzihlukanisa, umthelekisi owahlukileyo ufumana ulwazi lotshintsho lwengqiqo, emva koko usete okanye usete kwakhona i-flip-flop kunye nesekethe yemveliso ngokufanelekileyo. Uhlaziyo lwamaxesha athile luthunyelwa ngapha komqobo ukuqinisekisa umgangatho ofanelekileyo we-dc wesiphumo. Ukuba le dc-refresh pulse ayifunyanwanga zonke ii-4 μs, igalelo lithathwa ngokuba alinamandla okanye aliqhutywa ngokusebenzayo, kwaye isekethe ye-failsafe iqhubela imveliso kwimo ephezulu ye-logic.
I-capacitance encinci kunye nexesha elibangelwa rhoqo libonelela ngokusebenza ngokukhawuleza kunye namazinga okubonisa afumaneka kwi-0 Mbps (DC) ukuya kwi-150 Mbps (Izinga lokubonisa umgca linani lokuguqulwa kombane olwenziwa ngesibini esichazwe kwiiyunithi ze-bps). I-Aoption, i-B-option, kunye ne-C-option izixhobo zineengeniso ze-TTL ze-input kunye nesihluzo sengxolo kwigalelo elithintela i-pulses edlulayo ukuba idluliselwe kwimveliso yesixhobo. Izixhobo zokhetho lwe-M zineCMOS VCC/2 ingeniso yokufaka kwaye azinasihluzo sengxolo yokufaka kunye nolibaziseko olongezelelweyo losasazo.
I-ISO7220x kunye ne-ISO7221x intsapho yezixhobo zifuna i-voltages ezimbini zokubonelela nge-2.8 V (C-Grade), 3.3 V, 5 V, okanye nayiphi na indibaniselwano. Onke amagalelo akwi-5-V enyamezelayo xa enikezelwa ukusuka kwi-2.8-V okanye i-3.3-V unikezelo kwaye zonke iziphumo ziyi-4-mA CMOS. I-ISO7220x kunye ne-ISO7221x usapho lwezixhobo luphawulwe ukusebenza kuluhlu lobushushu obuku-40°C ukuya +125°C.
