♠ Isantya esiphezulu seCMOS esiNgqongileyo esiBuyiselwa kwiMultivibrators eMonostable enoSeta kwakhona
I-'HC123, 'HCT123, CD74HC423 kunye ne-CD74HCT423 zii-multivibrators eziphindwe kabini ezinokusetha ngokutsha.Zonke ziyakwazi ukubuyiswa kwaye zihluke kuphela kwiindidi ze-123 zinokuthi ziqhutywe yi-negative ukuya kwi-pulse yokusetha kabusha okulungileyo;ngelixa iindidi ezingama-423 zingenalo olu phawu.I-resistor yangaphandle (RX) kunye ne-capacitor yangaphandle (CX) ilawula ixesha kunye nokuchaneka kwesekethe.Ukulungelelaniswa kwe-Rx kunye ne-CX inikezela ngoluhlu olubanzi lwemveliso yobubanzi be-pulse ukusuka kwii-terminals ze-Q kunye ne-Q.I-Pulse triggering kwi-A kunye ne-B igalelo lenzeka kwinqanaba elithile lombane kwaye alihambelani nokunyuka nokuwa kwexesha le-trigger pulses.
Emva kokuba kuqhutywe, i-output pulse wide inokwandiswa ngokubuyisela kwakhona ii-inputs A kunye ne-B. I-pulse ye-output inokupheliswa ngezinga eli-LOW kwi-Reset (R) ipini.I-trailing edge triggering (A) kunye ne-edge edge triggering (B) iingeniso zibonelelwa ngokuqalisa ukusuka nakuwuphi na umgca we-pulse.Ukuba mhlawumbi iMono ayisetyenziswanga igalelo ngalinye kwisixhobo esingasetyenziswanga (A, B, no-R) mayiyekiswe phezulu okanye phantsi.Ubuncinci bexabiso lokuchasana kwangaphandle, i-Rx iqhelekile yi-5kΩ.Ixabiso elincinci amandla angaphandle, CX, yi-0pF.Ukubalwa kobubanzi be-pulse yi-tW = 0.45 RXCX kwi-VCC = 5V
• Ukuthathela indawo ukuSeta kwakhona kukuphelisa i-Output Pulse
• Ukuqalisa ukusuka kuMda oKhokelayo okanye oLalayo
• Ii-Q kunye ne-Q ezigcinwe kwi-Buffered Outputs
• Ukwahlula Ukusetha kwakhona
