Variable duty cycle monostable multivibrator composed of 74HCT221

Published:2011/4/13 3:17:00 Author:Ecco | Keyword: Variable duty cycle, monostable multivibrator

The chart shows the variable duty cycle monostable multivibrator composed of 74HCT221. Capacitor C is charged and discharged at the same rate, the duty cycle is 50%, the oscillation period T = RC. The R in figure (a) can be replaced by the map to get other desired duty cycle, during this time, Cl is charged by R1, and discharged by R2, the oscillation period T = (R1 + R2) C / 2, the duty cycle is approximately Rl / (R1 + R2). In the figure 9-11, VDl, VD2, VD3 is the 1N4148.   (View)
