Isibali sikhathi/i-oscillator ye-MIC1555 IttyBitty CMOS RC kanye ne-oscillator ye-MIC1557 IttyBitty CMOS RC yakhelwe ukuhlinzeka ngamapulses ukusuka kumzila wesitimela ukuya kusitimela ukuze kubambezeleke isikhathi esinembile noma ukukhiqizwa kwamafrikhwensi.
Lawa madivayisi ayafana ngokusebenza nezinga lembonini elithi “555”, ngaphandle kwephinikhodi yokulawula imvamisa (FC) noma iphinikhodi yokukhipha i-open-collector (D). Iphinikhodi ye-threshold (THR) ihamba phambili ngaphezu kokufaka i-trigger (TRG), iqinisekisa ukuthi okukhiphayo kwe-BiCMOS kuvaliwe uma i-TRG iphezulu.
I-MIC1555 ingasetshenziswa njenge-astable (i-oscillator) noma i-monostable (i-shot eyodwa) enomkhawulo ohlukene kanye nokokufaka kwe-trigger. Kumodi yokushutha okukodwa, ububanzi be-pulse okukhiphayo kulawulwa ngokunembile yi-resistor yangaphandle kanye ne-capacitor. Ukubambezeleka kwesikhathi kungase kulawulwe ngokunembile ukusuka kuma-microsecond ukuya emahoreni. Kumodi ye-oscillator, okukhiphayo kusetshenziselwa ukunikeza impendulo enembayo, ngobuncane be-resistor eyodwa kanye ne-capacitor eyodwa ekhiqiza igagasi lesikwele lomjikelezo womsebenzi ongu-50%.
I-MIC1557 yakhelwe ukusebenza kwe-astable (oscillator) kuphela, ngokokufaka kwe-chip select/set (CS) yokuvala amandla aphansi. I-resistor eyodwa kanye ne-capacitor eyodwa inikeza i-50% ye-duty cycle wave wave. Ezinye izilinganiso zomjikelezo wemisebenzi zingakhiqizwa kusetshenziswa ama-diode amabili nama-resistors amabili.
I-MIC1555/7 inikwe amandla ukusuka ku-+2.7V kuya ku-+18V kagesi wokunikezela futhi ilinganiselwe ku--40°C kuya ku-+85°C ibanga lokushisa elizungezile. I-MIC1555/7 iyatholakala ku-SOT-23-5, namaphakheji amancane we-SOT23-5 5-pin. Iphrofayili ephansi, inguqulo ye-UTDFN ezacile kakhulu ye-MIC1555 (enokukhethwa kwe-chip) nayo iyatholakala.
