Intshayelelo

I-isolator yedijithali yi-chip kwinkqubo ye-elektroniki apho i-digital kunye ne-analog signals zihanjiswa khona, ukuze zibe neempawu eziphezulu zokumelana nokuzimela ukuze zifezekise ukuhlukaniswa phakathi kwenkqubo ye-elektroniki kunye nomsebenzisi.Abaqulunqi bazisa ukuzihlukanisa ukuhlangabezana nemimiselo yokhuseleko okanye ukunciphisa ingxolo ye-loop yomhlaba.Ukuhlukaniswa kwe-galvanic kuqinisekisa ukuba ukuhanjiswa kwedatha akukho ngokusebenzisa uxhulumaniso lombane okanye iindlela zokuvuza, ngaloo ndlela ukuphepha umngcipheko wokhuseleko.Nangona kunjalo, ukwahlukaniswa kubeka imida kwi-latency, ukusetyenziswa kwamandla, iindleko kunye nobukhulu.Injongo ye-digital isolator kuhlangabezana neemfuno zokhuseleko ngelixa unciphisa iziphumo ezibi.

Ingcaciso yeMveliso

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 njengelingenawo amandla okanye aliqhutywanga, kwaye i-failsafe circuit iqhubela imveliso ukuya kwi-logic ephezulu.
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-A-option, 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 songeniso lwengxolo kunye nokulibaziseka okongeziweyo kosasazo.
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.

Ngaphambili: Izinto ezintsha zoqobo ze-elektroniki, ezishushu ezithengisa i-ISO1050DUBR
