Working Principles

The TS556IN is a dual timer and oscillator IC that operates based on the principles of RC timing. It consists of two independent 555 timer circuits integrated into a single package. Each timer can be configured as a monostable (one-shot) or astable (oscillator) mode.

In the monostable mode, the timing interval is determined by an external resistor and capacitor connected to the appropriate pins. Upon triggering, the output remains high for a duration determined by the RC time constant.

In the astable mode, the timing interval is determined by the same external resistor and capacitor. The output oscillates between high and low states, creating a square wave with a frequency determined by the RC time constant.
