The sequential timer application chains together multiple monostable timers. The joining components are the
33-kΩ resistors and 0.001-µF capacitors. The output high to low edge passes a 10-µs start pulse to the next monostable. A diode is needed to prevent over voltage on the trigger input when on the previous output's low to high edge.
