Working Principles

The TLC555QDRQ1 is a timer IC that operates based on the charging and discharging of an external capacitor. In monostable mode, the output pulse width is determined by the values of an external resistor and capacitor. In astable mode, the IC oscillates between two states, generating a continuous square wave output.
