I-CAD Design for 74hc02

Ukuhlaziywa okuphelele kwe-74Hc02

Le khasi 74hc02 yi-quad 2-okokufaka noma isango ic enama-diode ezakhelwe ezakhelwe ngaphakathi kokufaka, ukuvumela ukuxhumana nama-voltages ngenhla V_Cc lapho isetshenziswa ngokumelana nokukhawulelwa kwamanje.Isebenza ngaphezu kwe-2V kuya ku-6V Supply Range, okwenza ukuthi ihambisane nawo womabili amazinga we-TTL nama-CMOS Logic.I-74HC02 ilungele izinhlelo zokusebenza ezibonakalayo zedijithali ezidinga imisebenzi ethembekile noma yesango, ukusebenza okuguquguqukayo kwe-voltage ukuxhumanisa, nokusebenza kahle emibuthanweni yamandla aphansi.

Izici ze-74HC02

Uhla olubanzi lwamandla kagesi

I-74HC02 isebenza ngaphandle komthungo ngama-voltages enikezela kusuka ku-2.0V kuya ku-6.0V.Lokhu kuhambisana okubanzi kuvumela ukuhlanganiswa nesethi ehlukahlukene yemiklamo yesifunda, ukuthola amadivaysi asebenza kumabhethri anamandla anamandla kanye nezinhlelo eziyinkimbinkimbi ze-elekthronikhi.Sithola lokhu kuguquguquka okuwusizo lapho ubuciko bokuqamba imikhiqizo ngezindawo ezahlukahlukene.

Ukusetshenziswa kwamandla okusebenzayo

Ukuba yidivaysi ye-CMOS, izici ezingama-74HC02 zehlise ukusetshenziswa kwamandla, ukuthuthukisa isikhathi sokuphila samadivayisi asuselwa kubhethri kanye nokunciphisa izindleko zamandla kuma-setups amakhulu.Kuhlelo lokusebenza lweselula futhi olushumekiwe, idrayivu eya kwizakhi ezisebenza ngamandla amandla iyanda kakhulu, ihambisana nezinhloso ezibanzi zemvelo ukunciphisa umthelela wezemvelo.

Ukuvikelwa kwe-Audivease

Amandla we-74hc02 wokuhlukanisa ukuphazamiseka kukagesi okungafuneki kuqinisekisa ukusebenza okungaguquki ngisho nokuphazamiseka okuphezulu kwe-electromagnetic.Le mfanelo ukusekela ubuqotho besiginali, ikakhulukazi ezindaweni zezimboni noma emabhodini okujikeleza agcwele kakhulu lapho ukuphazamiseka kuyinselelo eqhubekayo.

Ukuvikela okuqinile kwe-latch

Ebonisa amandla we-latch-up Amandla adlula ama-100 maisuselwe kumazinga wama-3D 78, ama-74hc02 akhombisa ukuqina okuhlukile.Amandla awo okumelana nokumelana nokuvimbela ukuvikela amasekethe kusuka ekuhlulekeni okungenzeka, ngaleyo ndlela aqinise ukuthembeka kohlelo lonke.Lesi sici sifakazela okunenzuzo ezimeni ngokunciphisa izidingo zokulungiswa kanye nokwelula isikhathi sokuphila kwamadivayisi.

Ukubambelela kumazinga we-Logic Level

Isebenza emazingeni e-CMOS, umehluko we-74HC02 nge-TTL-i-74Hct02, zombili zivumelana namazinga we-Jedec.Lokhu kwehluka kuvumela ukuzivumelanisa nezimo eziguqulweni ezahlukahlukene zokuqonda, ngaleyo ndlela kunciphise ukuhlanganiswa kwezakhiwo zomjikelezo wedijithali ezahlukahlukene.Sikuthola kuqondile ukuvumelanisa lezi zingxenye ngehadiware ekhona ngaphambili, okuholela ekuvumelanisweni okuthuthukile kanye nemikhawulo embalwa yokwakheka.

Ukuvikelwa ekukhiphekeni kwe-electrostatic (ESD)

Ihlotshiswe nge-ESD SafeGards ebambelela kumazinga we-HBM kanye ne-MM, i-74HC02 ivikeleke kahle izigameko zokukhishwa kwe-statetic.Lokhu kusiphatha nokufakwa, izigaba lapho ugesi oluqinile lungabeka khona izingozi ezinkulu.Ngokunamathela emikhubeni engcono kakhulu ekuphathweni kwe-ESD, singanciphisa amathuba okulimala kwengxenye nokwehluleka.

Ukupakishwa okuguquguqukayo nokubekezelela izinga lokushisa

Ngezinketho ezahlukahlukene zokufaka, i-74HC02 ihlangabezana nezicelo zohlelo lokusebenza ezahlukahlukene, zibonisa ukuzivumelanisa nezimo kuzo zombili izilungiselelo ezilinganiselwe.Ukushisa kwayo kokushisa kusuka ku-50 ° C kuya ku- + 125 ° C kuqinisekisa ukuthembeka ezimweni ezimbi kakhulu, kusuka kumasethingi angaphandle we-frigid ezindaweni zokugibela izimboni.Lokhu kuvumelana kuvame ukuthola izinhlelo zokusebenza lapho kugcinwa khona ukusebenza okungaguquki naphezu kokushisa v ariat ion kuthathwa njengokudingwa.

Ukucaciswa kobuchwepheshe

I-74HC02 isebenza kahle ngaphakathi kwebanga le-voltage epanning kusuka ku-2V kuya ku-6V, ukukhuthaza ukuvumelana nezimo kuzinhlelo eziningi zedijithali.Ngokukhululeka, ama-melds abe yimibuthano yamanje ngenxa yalolu banga.Ngokufanayo, i-Nexperia USA Inc. I-74Hc02BQ, 115 Inikeza i-voltage spectrum efanayo, igcizelela ukusebenza kwayo okubanzi ezimeni ezahlukahlukene zobuchwepheshe.Nansi imininingwane, izimfanelo, amapharamitha we-NEXPERIA USA Inc. 74hc02BQ, 115.
