Chithunzi cha SN75LBC176D
Ma SN55LBC176, SN65LBC176, SN65LBC176Q, ndi SN75LBC176 ma transceivers osiyanitsira mabasi ndi mabwalo ophatikizika omwe amapangidwira kuti azilumikizana ndi ma data pamizere yamabasi ambiri.Amapangidwira mizere yopatsirana bwino ndipo amakumana ndi ANSI Standard TIA/EIA-485-A (RS-485) ndi ISO 8482:1987(E).
SN55LBC176, SN65LBC176, SN65LBC176Q, ndi SN75LBC176 imaphatikiza ma 3-state, oyendetsa mzere wosiyana ndi wolandila mzere wolowera, onsewa amagwira ntchito kuchokera kumagetsi amodzi a 5-V.Dalaivala ndi wolandira ali ndi mphamvu yogwira-mkulu ndi yogwira-otsika, motero, yomwe imatha kugwirizanitsa pamodzi kuti igwire ntchito ngati chiwongolero chowongolera.Zotulutsa zosiyanitsira madalaivala ndi zolowetsa zosiyanitsira zimalumikizana mkati kuti apange doko la mabasi osiyanitsira/kutulutsa (I/O) lomwe lapangidwa kuti lipereke kutsitsa pang'ono ku basi nthawi iliyonse dalaivala ali wolumala kapena V.CC= 0. Doko ili lili ndi ma voltages ambiri abwino komanso oyipa, zomwe zimapangitsa chipangizocho kukhala choyenera kugwiritsa ntchito pamzere wachipani.Kutsika kwambiri kwa kachipangizo kachipangizo kamakono kungapezeke mwa kulepheretsa dalaivala ndi wolandira.
Ma transceivers awa ndi oyenera ANSI Standard TIA/EIA-485 (RS-485) ndi ISO 8482 mapulogalamu mpaka momwe afotokozedwera pamikhalidwe yogwirira ntchito ndi mawonekedwe a pepalali.Malire ena omwe ali mu TIA/EIA-485-A ndi ISO 8482:1987 (E) sakukwaniritsidwa kapena sangayesedwe pamlingo wonse wa kutentha kwankhondo.
SN55LBC176 imagwira ntchito kuyambira -55 ° C mpaka 125 ° C.SN65LBC176 imadziwika kuti ikugwira ntchito kuyambira -40 ° C mpaka 85 ° C, ndipo SN65LBC176Q imagwira ntchito kuchokera -40 ° C mpaka 125 ° C.SN75LBC176 imagwira ntchito kuchokera ku 0 ° C mpaka 70 ° C.
1. Kodi ogwira ntchito m'dipatimenti yanu ya R & D ndi ndani?Kodi ziyeneretso zanu ndi zotani?
-R & D Mtsogoleri: pangani dongosolo la nthawi yayitali la R & D ndikumvetsetsa momwe kafukufuku ndi chitukuko;Kuwongolera ndi kuyang'anira dipatimenti ya r&d kuti ikwaniritse njira zamakampani ndi mapulani apachaka a R&D;Kuwongolera kupita patsogolo kwa chitukuko cha mankhwala ndikusintha dongosolo;Khazikitsani gulu labwino kwambiri la kafukufuku wazinthu ndi chitukuko, kufufuza ndi kuphunzitsa ogwira ntchito zaukadaulo.
Woyang'anira R & D: pangani mankhwala atsopano a R & D ndikuwonetsa kuthekera kwa dongosolo;Kuyang'anira ndi kuyang'anira momwe ntchito ya R&d ikuyendera;Fufuzani zachitukuko chazinthu zatsopano ndikupereka mayankho ogwira mtima malinga ndi zomwe makasitomala amafuna m'magawo osiyanasiyana
Ogwira ntchito ndi R&d: sonkhanitsani ndikusankha zofunikira;Mapulogalamu apakompyuta;Kuyesa, kuyesa ndi kusanthula;Konzani zida ndi zida zoyeserera, zoyeserera ndi kusanthula;Lembani deta yoyezera, pangani mawerengedwe ndikukonzekera ma chart;Chitani kafukufuku wamawerengero
2. Kodi lingaliro lanu la kafukufuku ndi chitukuko ndi chiyani?
- Lingaliro lazinthu ndi kusankha kwazinthu ndikuwunika tanthauzo lazinthu ndi kapangidwe ka pulani ya projekiti ndi kuyezetsa kwachitukuko ndikutsimikizira kukhazikitsidwa kwa msika
