Emhlabeni oyinkimbinkimbi we-elektroniki umjikelezo we-elekthronikhi, ukumelana nokudonsa okuhlanganisa ngaphezu kwamadivayisi nje wokunciphisa ukugeleza kwamanje;ziyizifiso zokuqinisekisa ukuqina kwezesekethwa.Inselelo yabaqambi balele ekutholeni okucashile kokudonsa nokudonsa phansi, kuvame ukukhubeka ngenxa yokuntuleka kokuqonda okuphelele.
Ukuqonda okusebenzayo kanye nokuhlangenwe nakho kwesicelo
Ukusebenzisa ukumelana kokudonsela phansi ngokungafanele kungakhuthaza kakhulu ukusebenza nokwethenjwa kwemibuthano kagesi.Ngezansi kunezifundo zamacala zigqamisa umsebenzi wazo ezimeni ezahlukahlukene:
Ukuthuthukiswa kokuhambisana kwe-Intercet: Ukuvala ama-TTL kanye ne-CMOS Palcuits kuveza izinselelo, ikakhulukazi lapho izinga eliphakeme le-TTL lingahlangabezani nemfuneko ephansi ye-CMOS (ngokujwayelekile 3.5v).Ukuphikiswa kokudonswa kokukhishwa kwe-TTL kungaphakamisa ngempumelelo izinga lokukhipha, uqinisekise ukusebenza okungenamthungo.
I-Open-Drain (OC) yokukhipha umjikelezo: Ngemibuthano yokukhipha i-OC, ukufakwa komphikisi wokudonsa kubalulekile ekusebenzeni kahle.
Amandla okushayela e-Microcontroller okuphumayo
I-CMOS Chip Evik Heast: Ukuxhuma ukumelana nokudonsa kwezikhonkwane ezingenzi lutho kuma-CMO CHIPS kusiza ukuvimbela ukulimala kusuka kugesi ovuthayo ngokunciphisa indlela yokufaka ukuvikela umjikelezo.
Ubuqotho be-Signal kanye nokulwa nokuphazamiseka: Ukubeka ukumelana nokudonsela phansi ku-Chip Pins kuthuthukisa umsindo wesiginali nomjikelezo wokuphazanyiswa.Leliqhinga linenzuzo ikakhulukazi ezindaweni zokuphazamiseka okuphezulu noma ngesikhathi sokuhambisa amabanga amade, lapho ukumelana nokudonsela phansi kuvikela khona ukuphazamiseka kwe-electromagnetic.
Ukumelana nokuphazamiseka nokuboniswa kwesiginali
Izindlela zokukhetha zamanani wokuphikiswa kokudonsa
Ukukhetha inani lokuphikiswa okuphelele kokudonsela phansi kubalulekile, kuthinta ukusebenza kwesekethe.Ukukhetha kuhilela ukucubungula:
Ukusetshenziswa kwamandla vs Ukusetshenziswa kwamandla vs Ukulingana kokulingana kwe-Equilibrium: Amandla we-Resistance Advances ezilinganisweni ezifanelekayo ngokusetshenziswa kwamandla okuncane.
Izidingo Zokushayela Ezisezingeni eliphansi: Ukuhlola Izidingo Zokushayela Umjikelezo Wezinga Elincane kubalulekile ekukhetheni inani elifanele lokuphikisa.
Imibuthalo ephezulu futhi ephansi
