Working Principles

LM393PWR works by comparing the voltages applied to its non-inverting and inverting inputs. If the voltage at the non-inverting input is higher than the voltage at the inverting input, the output will be high (logic level 1). Conversely, if the voltage at the inverting input is higher, the output will be low (logic level 0).
