Working Principles

The TLC555CPSR operates based on the principles of an astable or monostable multivibrator. In astable mode, the timing capacitor charges and discharges through the timing resistor, generating a continuous square wave output. In monostable mode, a trigger signal initiates a timing interval, during which the output remains high for a specific duration determined by the timing resistor and capacitor values.
