Stable controller capable of producing accurate time delays or oscillation. The 556 is a dual 555. Timing is provided by. an external resistor and capacitor for each timing function. J2. only Vqc and ground. The circuits may be triggered and. reset on falling waveforms. The output structures may sink. or source 150mA. Low State. Note 1.
The 555 timer consists of two voltage comparators, a bistable flip-flop, a discharge transistor, and a resistor divider network. To understand the basic concept of the timer let’ s first examine the timer in block form as in Figure 1. The resistive divider network is used to set the comparator levels.

The LM555 is a highly stable controller capable of pro-ducing accurate timing pulses. With a monostable opera-tion, the delay is controlled by one external resistor and one capacitor. With astable operation, the frequency and duty cycle are accurately controlled by two external resistors and one capacitor.
The 555 monolithic timing circuit is a highly stable controller capable of producing accurate time delays, or oscillation. In the time delay mode of operation, the time is precisely controlled by one external resistor and capacitor.
