Dhonza ikozvino uye yekudiridza ikozvino maparameter ekuyera dunhu rinobuda dhiraivha kugona (chiziviso: kudhonza nekudiridza zvese ndezvekupera kwekubuda, saka ndiyo simba remutyairi) parameters. Ichi chirevo chinowanzoshandiswa mumaseketi edhijitari.
Pano tinofanira kutanga kutsanangura kuti kudhonza uye kudiridza ikozvino muchinyorwa chip chiremerera parameter ukoshi, inova yokumusoro muganhu goho chigumo kudhonza uye kudiridza ikozvino redunhu chaiko (akabvumirwa kunonyanyisa tsika).
Pfungwa ichataurwa pazasi ndiyo chaiyo kukosha mudunhu.
Nekuti kubuda kwemaseketi edhijitari kunongokwira, kwakaderera (0, 1), kukosha kwemagetsi:
Kana iyo yepamusoro-level inobuda yabuda, iyo inobuda inowanzopihwa kumutoro. Kukosha kwezvino kunonzi "dhonza ikozvino";
Kana iyo yakaderera-level inobuda kazhinji iri ikozvino kutora mutoro, kukosha kweiyo absorption ikozvino kunonzi "kudiridza (pinda) ikozvino".
Pamudziyo wekushandisa ikozvino:
Iyo inouya ikozvino uye yekunyudza ikozvino ndeyekuisa. Ikozvino ndeyekungoita, uye iyo yekunyura ikozvino inoshanda.
Kana yekunze ikozvino inopfuura nepapini yepini, iyo 'inoyerera' mune chip inonzi yekudiridza ikozvino (iri kudiridzwa);
Sezvineiwo, kana iyo yemukati ikozvino kuburikidza ne chip pin kubva kune chip 'inoyerera' inonzi dhonza ikozvino (kuburitswa kunze);
Sei ndichigona kuyera kubuda kwekutyaira kugona? Mharadzano
Kana iyo inonzwisisika gonhi inobuda yakaderera, yazvino inodiridzwa mugonhi re logic inonzi irrigation current. Iyo yakakura yekudiridza ikozvino, iyo yakakwirira yakaderera mwero wekubuda kunopera. Iyo inogona zvakare kuoneka kubva kune yakabuda maitiro curve ye triode. Iyo yakakura yekudiridza ikozvino, yakakura iyo saturated voltage inodonha, uye yakakura iyo yakaderera mwero. Nekudaro, iyo yakaderera mwero weiyo logic gonhi ishoma, uye ine yakanyanya UOLMAX. Paunenge uchishanda pamusuwo we logic, hazvibvumidzwe kudarika kukosha uku. Zvinotsanangurwa zveTTL logic gonhi zvinotsanangura UOLMAX ≤0.4 ～ 0.5V. Nokudaro, kune muganhu wepamusoro wekudiridza ikozvino.
Kana iyo inonzwisisika gonhi yekubuda inopera yakakwira, yazvino pamusuwo unonzwisisika wekubuda kunopera uri kubuda kunze kwemusuwo welogic. Ikozvino iyi inonzi pull current. Iyo yakakura iyo yekudhonza ikozvino, iyo yakaderera iyo yakakwirira mwero wekubuda kunopera. Izvi zvinodaro nekuti iyo inobuda -level triode ine yemukati kuramba, uye kudonha kwevoltage pane yemukati kuramba kunoderedza kubuda kwemagetsi. Iyo yakakura iyo yekudhonza ikozvino, iyo yakaderera iyo yakakwirira mwero wekubuda kunopera. Nekudaro, iyo yakakwira mwero weiyo logic gonhi ishoma, uye ine hushoma UOHmin. Paunenge uchishanda mumusuwo we logic, hazvibvumirwi kudarika kukosha uku. Izvo zvinotsanangurwa zveTTL logic yemusuwo zvinotsanangurwa uohmin ≥2.4V. Nokudaro, kunewo muganhu wepamusoro wekudhonza ikozvino.
Zvinogona kuonekwa kuti kune muganhu wepamusoro pakudhonza ikozvino uye kudiridza ikozvino pamagumo ekubuda. Zvikasadaro, kana iyo yepamusoro yakabuda, iyo yekudhonza ikozvino inodzikisa iyo yekubuda level pane UOHMIN; kana iyo yakaderera-level inobuda, yekudiridza ikozvino ichaita kuti goho riwedzere kupfuura UOLMAX.
Naizvozvo, kudhonza uye kudiridza ikozvino kunoratidza kubuda kwekutyaira kugona. (Iyo yakakura iyo chip yekudhonza uye kudiridza ikozvino parameter kukosha, zvinoreva kuti chip inogona kubatanidza mitoro yakawanda, nekuti, senge yekudiridza ikozvino mutoro, iyo yakawanda mutoro;
Nekuti iyo yepamusoro-level yekupinda ikozvino idiki, paiyo micro-level level, kazhinji haina chikonzero chekufunga nezvayo. Iyo yakaderera level ikozvino yakakura uye pamilliamp level.
Naizvozvo, kazhinji hapana dambudziko nekudzika-level yekudiridza ikozvino. Shandisa feni kutsanangura kugona kwegonhi rine musoro kutyaira magonhi akafanana. Iyo feni kunze kwetsitsi ndeyereshiyo yeyakaderera-level yepamusoro yakabuda ikozvino uye yakanyanya kupinza ikozvino yeyakaderera nhanho.
Muchikamu chekubatanidza, kusveta ikozvino, kudhonza ikozvino kubuda uye kudiridza ikozvino kubudiswa ipfungwa inokosha zvikuru.
Dhonza kumusoro uye kuvuza, inoshanda yakabuda ikozvino, inobva kune inobuda inobuda ikozvino;
Kudiridza kuri kuchaja, passive input current, iyo inoyerera ichibva kune inobuda port;
Kutambura kuri kushingaira kufema ikozvino, iyo inoyerera ichibva pachiteshi chekupinza.
Ikozvino yekusveta uye yekudiridza ikozvino inoyerera ichipinda muchip kubva kunze redunhu rechip. Musiyano ndewekuti kunyura kwazvino kuri kushanda, uye ikozvino kunyura kunoyerera kubva kumagumo ekuisa chip. Ikozvino yekudurura isingaiti, uye ikozvino inoyerera kubva kumagumo inobuda inodanwa mune yazvino.
Iyo yekudhonza ikozvino ndiyo inobuda ikozvino yakapihwa nedhijitari yedunhu kubuda yakakwira mwero kumutoro. The goho yakaderera mwero kana kudiridza ikozvino ari yokupinza ikozvino kudhijitari redunhu. Ndivo chaizvo zvokupinza uye goho zvazvino kugona.
The absorption current is for the input terminal (input end input), uye yekudhonza current (output end ichiyerera kunze) and the irrigation current (inozobuda inodiridzwa) inobuda.
