Working Principles

The TLV3404IDG4 is a voltage comparator that compares the voltages at its two inputs, IN1+ and IN1-. The output, OUT1, switches to a low state when the voltage at IN1- is higher than the voltage at IN1+. Conversely, the output switches to a high state when the voltage at IN1+ is higher than the voltage at IN1-. This behavior allows the IC to perform precise voltage level comparisons.
