A monostable Circuit Court muaj IC (integrated circuit), feem ntau yog ib qho khoom siv hu ua 555 sijhawm , nrog rau sab nraud tsis kam thiab sab nraud capacitance. Tom qab lub sijhawm ncua sijhawm t tau dhau mus, lub monostable Circuit Court rov qab mus rau lub xeev qis.

Hauv qhov no, lub monostable 555 timer ua haujlwm li cas?

Monostable 555 Timer Thaum muaj qhov tsis zoo (0V) mem tes yog siv rau qhov kev tawm tswv yim (pin 2) ntawm tus Monostable teeb tsa 555 Timer oscillator, tus sib piv sab hauv, (tus sib piv No1) kuaj pom cov tswv yim no thiab "tso" lub xeev ntawm flip-flop, hloov cov zis los ntawm lub xeev "LOW" mus rau lub xeev "HIGH".

Ib yam li ntawd, lub tshuab monostable tau txais nws lub npe li cas? Ib yam li ob lub xeev pulse generator configuration yog hu ua Monostable Multivibrators. Monostable Multivibrators tsuas muaj ib lub xeev ruaj khov (li no lawv lub npe : "Mono"), thiab tsim ib qho kev tawm suab paj nruag thaum nws yog ua rau sab nraud.

Li ntawd, koj ua li cas 555 timer?

Ua rau : Pin 2 ua rau , uas ua hauj lwm zoo li ib tug oob khab lub pistol pib lub 555 timer ua khiav. Cov ua rau yog active qis ua rau , uas txhais tau tias cov sijhawm pib thaum voltage ntawm tus pin 2 poob rau hauv qab ib feem peb ntawm cov khoom siv hluav taws xob. Thaum lub 555 yog ua rau ntawm tus pin 2, cov zis ntawm tus pin 3 mus siab.

Vim li cas IC 555 hu ua Timer?

Cov 555 Timer IC tau txais nws lub npe los ntawm peb 5KΩ resistors uas yog siv nyob rau hauv nws voltage divider network. Qhov no IC muaj txiaj ntsig zoo rau kev tsim cov sijhawm ncua sijhawm thiab oscillations.
