Working Principles

TLV3404IPW operates based on the principle of comparing two input voltages and providing a digital output based on the comparison result. Each comparator within the IC compares the voltage at its inverting (-) input with the voltage at its non-inverting (+) input. If the inverting input voltage is higher than the non-inverting input voltage, the output goes low (0). Conversely, if the non-inverting input voltage is higher, the output goes high (1).
