Mbiri ya MIC1557YM5TR
• + 2.7V mpaka + 18V Ntchito
• Pansi Pakalipano - <1 μA Njira Yoyimitsa Yoyimitsa (MIC1557) - 200 μA Yodziwika (TRG ndi THR Yotsika) pa 3V Supply
• Kusunga nthawi kuchokera ku Microseconds mpaka Maola
• "Zero" Choyambitsa Kutayikira ndi Zolowetsa za Threshold
• 50% Square Wave yokhala ndi One Resistor, One Capacitor
• Kulowetsa Kwambiri Kuposa Kulowetsa Kwachiyambi

The MIC1555 IttyBitty CMOS RC timer/oscillator ndi MIC1557 IttyBitty CMOS RC oscillator adapangidwa kuti azipereka masinthidwe a njanji kuti achedwetse nthawi kapena kutulutsa pafupipafupi.
Zidazi ndizofanana ndi ntchito yamakampani "555", popanda pini yowongolera pafupipafupi (FC) kapena pini yotulutsa (D). Pini yolowera pakhomo (THR) imakhala yoyamba kuposa cholowetsa (TRG), kuwonetsetsa kuti zotulutsa za BiCMOS zazimitsidwa TRG ikakwera.
MIC1555 ingagwiritsidwe ntchito ngati astable (oscillator) kapena monostable (imodzi-kuwombera) yokhala ndi malire osiyana ndi zolowetsa. Munjira yowomberedwa kumodzi, kutulutsa kwamphamvu kwamphamvu kumayendetsedwa ndendende ndi chopinga chakunja ndi capacitor. Kuchedwetsa nthawi kungawongoleredwe bwino kuyambira ma microseconds mpaka maola. Mu mawonekedwe a oscillator, zotulutsazo zimagwiritsidwa ntchito popereka mayankho olondola, okhala ndi chopinga chimodzi chocheperako ndi capacitor imodzi yomwe imatulutsa 50% yantchito yozungulira square wave.
MIC1557 idapangidwa kuti igwire ntchito ya astable (oscillator) yokha, yokhala ndi cholowetsa cha chip select/reset (CS) cha kutseka kwa mphamvu yotsika. Mmodzi wotsutsa ndi capacitor imodzi amapereka 50% ntchito yozungulira mafunde apakati. Magawo ena ozungulira atha kupangidwa pogwiritsa ntchito ma diode awiri ndi zopinga ziwiri.
Ma MIC1555/7 amayendetsedwa kuchokera ku +2.7V mpaka +18V voteji ndipo amavotera -40°C mpaka +85°C yozungulira kutentha osiyanasiyana. The MIC1555/7 akupezeka SOT-23-5, ndi woonda SOT23-5 5-pini phukusi. Mtundu wotsika kwambiri, wowonda kwambiri wa UTDFN wa MIC1555 (wokhala ndi chip select) umapezekanso.
