Inkcazelo ye-ULN2003A
Izixhobo ze-ULx200xA zine-voltage ephezulu, ephezulu yangoku ye-Darlington transistor arrays.Nganye iqulathe iiperi ezisixhenxe zeNPN yaseDarlington ebonisa iziphumo zevoltage ephezulu kunye ne-common-cathode clamp diode zokutshintsha imithwalo ye-inductive.
Umqokeleli-umlinganiselo wangoku wesibini esisodwa saseDarlington yi-500 mA.Izibini zaseDarlington zinokunxulunyaniswa nesakhono esiphezulu sangoku.Usetyenziso luquka abaqhubi be-relay, i-hammerdrivers, abaqhubi besibane, ukubonisa abaqhubi (i-LED kunye nokukhutshwa kwerhasi), abaqhubi bemigca, kunye ne-logic buffers.Ukwenzela i-100-V (ngaphandle kokutshintshelwa) iinguqulelo zezixhobo ze-ULx2003A, bonaSLRS023Idatha ye-SN75468 kunye ne-SN75469devices.
Isixhobo se-ULN2002A senzelwe ngokukodwa ukusetyenziswa kunye nezixhobo ze-PMOS ze-14-V ukuya kwi-25-V.Igalelo ngalinye lesi sixhobo sineZener diode kunye ne-resistor kuthotho ukulawula igalelo langoku ukuya kumda okhuselekileyo.Izixhobo ze-ULx2003A zine-2.7-kΩ isiseko sokumelana nesiseko kwi-Darlington nganye isibini sokusebenza ngokuthe ngqo kunye ne-TTL okanye i-5-V CMOS izixhobo.
Izixhobo ze-ULx2004A zine-10.5-kΩ isiseko sokuxhathisa ukuvumela ukusebenza ngokuthe ngqo kwizixhobo zeCMOS ezisebenzisa i-voltage yokubonelela nge-6 V ukuya kwi-15 V. Igalelo elifunekayo okwangoku le-ULx2004Adevice lingaphantsi kwezixhobo ze-ULx2003A, kwaye i-voltage efunekayo ingaphantsi kwe. efunwa sisixhobo se-ULN2002A.
1. Ngoobani abasebenzi kwisebe lakho le-R & D?Ziziphi iziqinisekiso zakho?
-R & D UMlawuli: yenza isicwangciso sexesha elide seR & D senkampani kwaye ubambe isikhokelo sophando kunye nophuhliso;Ukukhokela kunye nokulawula isebe le-r&d ukuphumeza isicwangciso se-r&d yenkampani kunye nesicwangciso sonyaka se-R&D;Lawula inkqubela phambili yophuhliso lwemveliso kwaye uhlengahlengise isicwangciso;Misela uphando lwemveliso egqwesileyo kunye neqela lophuhliso, uphicotho kunye noqeqesho olunxulumene nabasebenzi bobugcisa.
Umphathi we-R & D: yenza imveliso entsha ye-R & D isicwangciso kwaye ubonise ukwenzeka kwesicwangciso;Ukongamela kwaye ulawule inkqubela kunye nomgangatho womsebenzi we-r&d;Phanda ngophuhliso lwemveliso entsha kwaye ucebise izisombululo ezisebenzayo ngokweemfuno zabathengi kwiinkalo ezahlukeneyo
Abasebenzi be-R&d: ukuqokelela kunye nokusombulula iinkcukacha eziphambili;inkqubo yeKhompyutha;Ukuqhuba iimvavanyo, iimvavanyo kunye nohlalutyo;Lungisa izixhobo kunye nezixhobo zovavanyo, iimvavanyo kunye nohlalutyo;Ukurekhoda idatha yokulinganisa, yenza izibalo kwaye ulungiselele iitshathi;Yenza uphando lwamanani
2. Yintoni uphando lwakho lwemveliso kunye nombono wophuhliso?
-Umbono wemveliso kunye nokukhethwa kwemveliso kunye novavanyo lwenkcazo yemveliso kunye noyilo lwesicwangciso seprojekthi kunye novavanyo lwemveliso kunye nokuqinisekiswa kokuqaliswa kwintengiso
