Infinite Capacitor Oscillator

The LM555 is an integrated circuit that can accept analog signal to drive digital circuits.

Assuming \(V_{cc} = +5V\) and \(GND = 0V\)

It works as follows:

When pin 2 receives an input less than \( \frac {1}{3}\) of its \(V_{cc}\) , pin 3 will give an output of \(+5V\).

When pin 6 receives an input greater than \(\frac {2}{3}\) of its \(V_{cc}\), pin 3 will give an output of \(0V\).

When pin 3 is \(0V\), pin 7 is \(0V\).

When pin 3 is \(5V\), pin 7 has high impedance.

In the shown circuit, the LM 555 is configured as a clock circuit.

Calculate the period of OUT in seconds to the nearest hundreths.
