Ko te MIC1555 IttyBitty CMOS RC matawā/oscillator me te MIC1557 IttyBitty CMOS RC oscillator kua hangaia hei whakarato i nga pini tereina-ki-tereina mo te roanga o te wa tika, te whakaputa auau ranei.
Ko enei taputapu he rite tonu te mahi ki te paerewa ahumahi "555", kaore he pine mana auau (FC) ranei he titi tukunga-kohikohi tuwhera (D). Ko te titi paepae (THR) kei mua ake i te urunga keu (TRG), me te whakarite ka mutu te putanga BiCMOS ina he tiketike te TRG.
Ka taea te whakamahi i te MIC1555 hei astable (oscillator) he monostable ranei (kotahi-pere) me te paepae motuhake me nga whakauru keu. I roto i te aratau mapere kotahi, ko te whanui o te pupuhi whakaputa ka tino whakahaerehia e te parenga o waho me te punga. Ka taea te whakahaere tika mai i nga moroiti ki nga haora. I roto i te aratau oscillator, ka whakamahia te putanga ki te whakarato urupare tika, me te iti o te parenga kotahi me te puritanga kotahi e whakaputa ana i te ngaru tapawha 50%.
I hangaia te MIC1557 mo te mahi astabil (oscillator) anake, me te whakauru maramara whiriwhiri/tautuhi (CS) mo te iti o te hiko kati. Ko tetahi parenga me tetahi punga iahiko he 50% nga ngaru tapawha hurihanga mahi. Ko etahi atu owehenga huringa mahi ka mahia ma te whakamahi i nga diodes e rua me nga parenga e rua.
Ko te MIC1555/7 he hikoi mai i te +2.7V ki te +18V ngaohiko tuku, ka whakatauhia mo te -40°C ki te +85°C awhe pāmahana ambient. Kei te waatea te MIC1555/7 i roto i te SOT-23-5, me nga kohinga SOT23-5 5-pin angiangi. Kei te waatea ano he ahua iti, he putanga UTDFN tino kikokore o te MIC1555 (me te kowhiringa maramara).
