Kev piav qhia rau ULN2003A
Cov khoom siv ULx200xA yog high-voltage, high-tam sim no Darlington transistor arrays.Txhua tus muaj xya NPN Darlington khub uas muaj qhov ua haujlwm siab-voltage nrog cov-cathode clamp diodes rau kev hloov pauv inductive loads.
Kev ntsuas tam sim no ntawm ib khub Darlington yog 500 mA.Lub Darlington khub tuaj yeem ua ke kom muaj peev xwm siab dua tam sim no.Cov ntawv thov muaj xws li cov tsav tsheb relay, hammerdrivers, teeb tsav tsheb, tso saib tsav tsheb (LED thiab roj tso tawm), kab tsav tsheb, thiab cov logic buffers.Rau 100-V (lwm yam sib hloov) versions ntawm ULx2003A li, saib covSIB 023Cov ntaub ntawv rau SN75468 thiab SN75469 cov khoom siv.
ULN2002A ntaus ntawv yog tsim tshwj xeeb rau kev siv nrog 14-V to25-V PMOS li.Txhua lub tswv yim ntawm cov cuab yeej no muaj Zener diode thiab resistor nyob rau hauv series los tswj cov input tam sim no kom muaj kev txwv tsis pub dhau.Cov khoom siv ULx2003A muaj 2.7-kΩ series puag resistor rau txhua tus khub Darlington rau kev ua haujlwm ncaj qha nrog TTL lossis 5-V CMOS li.
Cov khoom siv ULx2004A muaj 10.5-kΩ series puag resistor tso cai rau kev ua haujlwm ncaj qha los ntawm CMOS cov khoom siv uas siv cov khoom siv hluav taws xob ntawm 6 V rau 15 V. Qhov xav tau tam sim no ntawm ULx2004Adevice yog qis dua ntawm cov khoom siv ULx2003A, thiab qhov yuav tsum tau muaj hluav taws xob tsawg dua. uas yuav tsum tau los ntawm ULN2002A ntaus ntawv.
