Working Principles

The LM139DRG4 operates based on the principle of comparing input voltages with a reference voltage. It consists of four independent voltage comparators, each with an inverting and non-inverting input. When the voltage at the non-inverting input is higher than the voltage at the inverting input, the corresponding output goes low. Conversely, when the voltage at the non-inverting input is lower, the output goes high.
