♠ High-Speed CMOS Logic Dual Retriggerable Monostable Multivibrators nrog Resets
Lub 'HC123, 'HCT123, CD74HC423 thiab CD74HCT423 yog dual monostable multivibrators nrog rov pib dua.Lawv tag nrho cov retriggerable thiab txawv tsuas yog nyob rau hauv uas 123 hom tuaj yeem tshwm sim los ntawm qhov tsis zoo rau qhov zoo rov pib mem tes;hos 423 hom tsis muaj qhov no.Ib qho hluav taws xob sab nraud (RX) thiab sab nraud capacitor (CX) tswj lub sij hawm thiab qhov tseeb rau lub voj voog.Kev hloov kho ntawm Rx thiab CX muab ntau yam ntawm cov zis pulse dav ntawm Q thiab Q terminals.Pulse triggering ntawm A thiab B inputs tshwm sim nyob rau hauv ib tug tshwj xeeb voltage theem thiab tsis muaj feem xyuam rau lub sij hawm nce thiab poob ntawm lub trigger pulses.
Thaum tshwm sim, cov zis pulse dav yuav txuas ntxiv los ntawm retriggering inputs A thiab B. Cov zis mem tes tuaj yeem raug txiav los ntawm qib qis ntawm Reset (R) tus pin.Trailing ntug triggering (A) thiab ua ntug triggering (B) inputs yog muab rau triggering los ntawm ib tug ntug ntawm lub input mem tes.Yog tias Mono tsis siv txhua qhov kev tawm tswv yim ntawm cov khoom siv tsis siv (A, B, thiab R) yuav tsum raug txiav tawm siab lossis qis.Qhov tsawg kawg nkaus tus nqi ntawm kev tiv thaiv sab nraud, Rx feem ntau yog 5kΩ.Qhov tsawg kawg nkaus tus nqi sab nraud capacitance, CX, yog 0pF.Kev suav rau pulse dav yog tW = 0.45 RXCX ntawm VCC = 5V
