♠ xx555 Precision Timers
Cov khoom siv no yog cov khoom siv hluav taws xob zoo tshaj plaws uas muaj peev xwm ua kom lub sijhawm qeeb lossis oscillation. Nyob rau hauv lub sij hawm ncua sij hawm los yog mono-stable hom ntawm kev ua hauj lwm, lub sij hawm ncua sij hawm yog tswj los ntawm ib tug tib sab nraud resistor thiab capacitor network. Hauv kev ua haujlwm ruaj khov, qhov zaus thiab lub luag haujlwm lub voj voog tuaj yeem tswj tau ntawm nws tus kheej nrog ob lub resistors sab nraud thiab ib qho tib lub capacitor sab nraud.
Qhov pib thiab theem pib ib txwm yog ob feem peb thiab ib feem peb, raws li, ntawm VCC. Cov theem no tuaj yeem hloov kho los ntawm kev siv lub tshuab hluav taws xob tswj-voltage. Thaum qhov kev tawm tswv yim hauv qab poob qis dua theem pib, lub flip-flop tau teeb tsa, thiab cov zis tawm mus siab. Yog hais tias tus txhais lus input yog siab tshaj tus trigger theem thiab qhov pib input yog siab tshaj qhov pib theem, lub flip-flop yog pib dua thiab cov zis yog tsawg. Qhov rov pib dua (RESET) cov tswv yim tuaj yeem hla dhau tag nrho lwm cov khoom siv thiab tuaj yeem siv los pib lub sijhawm tshiab. Thaum RESET poob qis, lub flip-flop rov pib dua, thiab cov zis tawm mus qis. Thaum cov zis qis qis, txoj kev qis impedance yog muab los ntawm kev tso tawm (DISCH) thiab hauv av. Cov zis hluav taws xob muaj peev xwm ntawm qhov dej los yog cov khoom tam sim no mus txog 200 mA. Kev ua haujlwm tau teev tseg rau cov khoom siv ntawm 5 V txog 15 V. Nrog rau 5-V cov khoom siv, cov qib tso zis tau sib xws nrog TTL cov khoom siv.
