555 monostable trigger timing circuit

  
Introduction to circuit schematic of the circuit shown in Figure 3-3. Here the 555 connected as a one-shot form, usually in a normally open push button switch
555 monostable trigger timing circuit - schematic

S-shaped state, pin output low 555. At this point the internal discharge switch Ij1 together, the voltage across capacitor C is zero. When you press the button switch S, the flip-flop flip, 555 feet from low to high, electrical path into the temporary steady state. After Zhe state time, the output end electrostatic level goes low. Transient time - as is the timing TW '- 1. 1RC. This circuit each press switch S, the circuit enters a given working condition once, so this circuit is brother to manually control the development work of the occasion. (2) Component Component selection parameters as shown in Figure 3-3 shows, wife no special requirements. (3) 555 monostable trigger timing circuit shown in Figure 3-3.
