Working Principles

The TLC339IDRG4 operates as a voltage comparator by comparing the voltages at its IN+ and IN- inputs. When the voltage at IN+ is higher than the voltage at IN-, the output goes low (0V) and when the voltage at IN+ is lower than the voltage at IN-, the output goes high (VCC). The open drain or push-pull output configuration determines the type of output signal.
