In this tutorial the 555 timer is examined in detail along with its uses, either by itself or in combination with other solid state devices. This timer uses a maze of transistors, diodes and resistors and for this complex reason a more simplified (but accurate) block diagram is used to explain the internal organizations of the 555.

Figure 2: Basic 555 monostable multivibrator circuit. Referring to the timing diagram in figure 3, a low voltage pulse applied to the trigger input (pin 2) causes the output voltage at pin 3 to go from low to high. The values of R1 and C1 determine how long the output will remain high.

The LM555/NE555/SA555 is a highly stable controller capable of producing accurate timing pulses. With monostable operation, the time delay is controlled by one external resistor and one capacitor. With astable operation, the frequency and duty cycle are accurately controlled with two external resistors and one capacitor.
The IC 555 is the most versatile linear integrated circuit introduced by signetics corporation. Fig. 1 shows the pin diagram and block diagram of NE 555 Timer. This is 8 pin IC timer. Fig.1 Function of Pins: Pin 1: Ground. All the voltages are measured with respect to this terminal. Pin 2: Trigger. The IC 555 uses two comparators.
