Due to these reasons 555 has a large number of applications and it is a popular ic among electronics hobbyists. Unlike monostable multivibrator mode it doesn't have any stable state, it has two quasi stable state (high and low). Therefore, f = 1/t =1.45/(ra+2rb)c.
For standard 555 timers use timing resistor values between 1k ohms and 1m ohms.
15 Astable Multivibrator Using 555 Timer Theory. Unlike monostable multivibrator mode it doesn't have any stable state, it has two quasi stable state (high and low). The frequency of the wave can be adjusted by changing the values of two resistors and a capacitor connected to the chip.
