555 Timer IC (LM555 / NE555 / SE555) Q8 C1

In the time-delay or monostable mode of operation, the timed interval is controlled by a single external resistor and capacitor network. In the astable mode of operation, the frequency and duty cycle can be controlled independently with two external resistors and a single external capacitor.

The threshold and trigger levels normally are two-thirds and one-third, respectively, of VCC. However, these levels can be altered by the use of the control voltage terminal. It has a wide input voltage range from 4.5V to 16V.
