Working Principles

The TS555ID is a monolithic timing circuit that operates as an astable or monostable multivibrator. It consists of a voltage-controlled oscillator, comparator, and flip-flop. The timing cycle is determined by the values of the external resistor and capacitor connected to the timing pins. In astable mode, the output signal oscillates between high and low states continuously. In monostable mode, the output signal remains high for a specific duration determined by the external components.
