Published:2012/7/23 3:10:00 Author:Ecco | Keyword: 555, dual astable multivibrator | From:SeekIC

The circuit includes two synchronized multivibrators which are composed ofone pair of 555time base circuits. The circuit can output two synchronized pulse signals ,and the spacing and frequency can be changed by adjusting the time constant. The circuit is flexible and convenient. When C1=C2=C, the oscillation frequency The ducy cycle depends on the value of R1 and R2, and it can reach 5% ~ 95%.
