Cov ntaub ntawv los yog datasheet: uas yog, qhov twg los tau thiab yuav ua li cas siv

Nyob rau hauv ib tug hais lus rau cov neeg muaj feem xyuam rau electronics, pom cov kab lus: "Peb yuav tsum tau mus ntsib tus datasheet." Yuav ua li cas yog meant thiab qhov twg kom tau txais cov proverbial datasheet?

Ib lo lus borrowed los ntawm lus Askiv thiab Ameslikas kaw raws li ib tug datasheet. Yog hais tias peb txhais nws rau hauv Lavxias teb sab, lus tau "ntaub ntawv daim ntawv". Ntawv comprise ntau yam ntawm pab kiag li lawm thiab hluav taws xob Cheebtsam. Nws yog yog li ntawd txoj cai hais tias cov datasheet - ib tug kev cov ntaub ntawv uas npaj los ntawm lub chaw tsim tshuaj paus.

Nrhiav datasheet Hauv Cheebtsam

Tej zaum nws yuav muaj tseeb hais tias xws li ib tug datasheet nti tom qab nws yog qhib. Tab sis lo lus nug yog: "Kuv yuav tau txais nws?"

Nyob rau hauv lub Soviet Union, ib tug zoo cov ntaub ntawv. Yog hais tias koj yuav tsum tau mus nrhiav cov ntaub ntawv nyob rau hauv ib tug transistor los yog nti, nws yog tsim nyog los noj lub uas tsim nyog kev taw qhia. Niaj hnub no, qhov yuav tsum tau rau cov phau ntawv reference zoo. Lawv hloov los ntawm cov kev tshawb fawb xyaw - txaus tsav ib lo lus datasheet thiab qhia kom meej lub npe ntawm tus yam ntaus ntawv. Qhov thib ob xaiv kom tau datasheet - mus rau ntawm qhov chaw, uas muaj cov ntaub ntawv thiab nws muaj mus nrhiav.

Specifications rau lub Cheebtsam yog muab raws li pdf ntaub ntawv. Qhib lawv ncaj qha nyob rau hauv lub browser.

Thawj nplooj datasheet

Thaum cov ntaub ntawv yog loaded rau lub computer, koj yuav tsum qhib cov datasheet. Yuav ua li cas yog nws muaj, dab tsi mus nrhiav ua ntej?

Ib tug yuav tsum pib los ntawm tus thawj page. Nws muab cov lus qhia yuav qhia ntau txog uniqueness ntawm ib tug ntaus ntawv, xws li ib tug dav ntau zaus, tsis tshua muaj zog noj, me me tsaus tam sim no.

Tsev Kev Specification muaj xws li:

• tivthaiv cov khoom (nta);
• piav qhia (piav qhia / kev piav qhia) ;
• configuration pins nyob rau hauv ib lub rooj los yog daim ntawv (pin configuration).

Nws yuav tsum muab sau tseg tias cov ntaub ntawv no tsis yog ib txwm txaus, yog li ntawd tsis txhob cia siab rau nws lig nws muaj nqis. Cov lus teb rau koj cov lus nug yuav mus nrhiav tau nyob rau hauv cov seem ntawm daim ntawv. Lub hom phiaj ntawm thawj nplooj ntawv - muab ib lub tswv yim hais txog nws, uas yog, qhia rau kuv seb yog.

Datasheet transistor piv rau hauv tib daim ntawv rau lub nti yog me me, yog li cov thawj nplooj ntawv tam sim ntawd qhia cov lus qhia txog nws cov tsis thiab kev twb kev txuas.

Cov ntsiab lus ntawm cov ntaub ntawv

Feem ntau cov feem ntau cov neeg siv nug txog lub datasheet: "Yog dab tsi thiab yuav ua li cas los nyeem nws?" Yog hais tias thawj lo lus nug mas suav hais tias, tus thib ob tau tsis tau yuav tsum tshawb.

Hauv engineers xyuam xim rau cov nram qab no ntawm cov ntaub ntawv.

• Pinout.

Nws qhia txog lub hom phiaj ntawm txhua tus pin nti los yog transistor. Designer tseem ceeb cov lus xaus rau npav Vcc thiab GND. Cov ntawm no yog rau cov mov voltage (feem ntau yog +5 V), lub thib ob - mus cuag cov "av". Microcontrollers yuav muaj ob peb yam ntawm cov lus xaus. Lawv qhov chaw nyob yog nyob ntawm lub cev ntaus (PDIP / TQFP / MLF).

• Tsav ntaus ntawv (Thaiv daim duab).

Nws qhia tau hais tias puab tivthaiv cov ntsiab lus. Piv txwv li, lub microcontroller uas qhia nws constituent nco, moos, input-output ports.

• Lub Circuit Court switching (Circuit Court Schematic).

Qhia txog qhov raug thaiv pab kiag li lawm. Nyob rau hauv kev xyaum circuits txawv los ntawm cov neeg qhia nyob rau hauv cov ntaub ntawv, vim nyob rau hauv txhua rooj plaub lub nti los yog transistor yog ib feem ntawm ib tug complex hluav taws xob ntaus ntawv, nyob rau hauv tag nrho cov uas nws Cheebtsam yuav tsum tau suav hais tias.

• Kub thiab hluav taws xob tsis.

Cov qhov tseem ceeb yog muab raws li los qhia cov dependence ntawm ib tug parameter ntawm lwm.

kawg tswv yim pom zoo

Novice tsim tawm ntawm hluav taws xob khoom yeej tsis to taub yuav ua li cas mus nyeem cov datasheet, dab tsi tswvyim ntawm tus ntaus ntawv thiab vim li cas pinout. Cuaj kaum nws yog pom zoo kom nyeem cov keeb kwm yav dhau cov ntaub ntawv uas thaum tsim ib yam khoom tshiab los yog kev kho ntawm faulty khoom.
