ULN2003APWR 50-V
Ibiranga ULN2003A
500-mA-Ikusanyirizo Ryakusanyirijwe hamwe (Ibisohoka rimwe)
Umuvuduko mwinshi w'amashanyarazi: 50 V.
Ibisohoka Clamp Diode
Inyongeramusaruro Zihuye nubwoko butandukanye bwa Logic
Porogaramu-Umushoferi
Ibisobanuro kuri ULN2003A
Ibikoresho bya ULx200xA ni voltage-nini cyane, ya tristoriste ya Darlington.Buri kimwe kigizwe na NPN ndwi ya Darlington igizwe na voltage-voltage isohoka hamwe na cathode clamp ya diode yo guhinduranya imitwaro ya inductive.
Ikusanyirizo-ryubu rya Darlington imwe ni 500 mA.Darlington jyenyine irasa nubushobozi bugezweho.Mubisabwa harimo abashoferi ba relay, inyundo, abamotari, abashoferi berekana (LED na gaze isohoka), abashoferi kumurongo, hamwe na bffers ya logique. Kubisobanuro 100-V (ubundi bisimburana) mubikoresho bya ULx2003A, reba kuriSLRS023urupapuro rwamakuru kuri SN75468 na SN75469devices.
Igikoresho cya ULN2002A cyashizweho kugirango gikoreshwe hamwe na 14-V kugeza 25-V PMOS.Buri cyinjizwa cyiki gikoresho gifite diode ya Zener hamwe na rezistor ikurikirana kugirango igenzure ibyinjira kugeza kumipaka itekanye.Ibikoresho bya ULx2003A bifite 2.7-kΩ y'uruhererekane rwibanze kuri buriDarlington kugirango ikoreshwe neza na TTL cyangwa 5-V CMOS.
Ibikoresho bya ULx2004A bifite rezo irwanya 10.5-kΩ kugirango yemere gukora biturutse kubikoresho bya CMOS bikoresha amashanyarazi ya 6 V kugeza 15 V. Ibisabwa byinjira byinjira muri ULx2004Adevice biri munsi yibikoresho bya ULx2003A, kandi voltage isabwa ni munsi ya ibyo bisabwa nigikoresho cya ULN2002A.
1. Ni bande bakozi mu ishami rya R & D?Ni ubuhe bushobozi bwawe?
-R & D Umuyobozi: gutegura gahunda yigihe kirekire yikigo no gusobanukirwa icyerekezo cyubushakashatsi niterambere;Kuyobora no kugenzura ishami rishyira mubikorwa ingamba za sosiyete na gahunda ya R&D yumwaka;Kugenzura iterambere ryibicuruzwa no guhindura gahunda;Shiraho ibicuruzwa byiza byubushakashatsi niterambere, kugenzura no guhugura abakozi ba tekiniki bijyanye.
Umuyobozi wa R & D: kora ibicuruzwa bishya R & D hanyuma werekane ko bishoboka gahunda;Kugenzura no gucunga iterambere nubuziranenge bwakazi;Kora ubushakashatsi ku bicuruzwa bishya kandi utange ibisubizo bifatika ukurikije ibyo umukiriya asabwa mubice bitandukanye
Abakozi & gukusanya: gukusanya no gutondekanya amakuru yingenzi;Porogaramu ya mudasobwa;Gukora ubushakashatsi, ibizamini nisesengura;Tegura ibikoresho nibikoresho byo kugerageza, kugerageza no gusesengura;Andika amakuru yo gupima, gukora ibarwa no gutegura imbonerahamwe;Kora ubushakashatsi bwibarurishamibare
2. Niki gitekerezo cyawe cyo gukora ubushakashatsi nibitekerezo byiterambere?
- Igitekerezo cyibicuruzwa no guhitamo ibicuruzwa nibisobanuro byerekana ibicuruzwa nibishushanyo mbonera byumushinga no kugerageza ibicuruzwa bitezimbere no kwemeza isoko
